Skype


Skype (IPA pronunciation: /skaɪp/, rhymes with type) is a proprietary peer-to-peer Internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA and competing against established open VoIP protocols like SIP or H.323. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. The system has a reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. Skype users can speak to other Skype users for free, call traditional telephone numbers for a fee (SkypeOut), receive calls from traditional phones for a fee (SkypeIn), and receive voicemail messages for a fee.

In September 2005, in a deal generally criticised by many as overpriced [1], eBay acquired the company for $US 2.6 billion in cash and stock, plus an additional 1.5 billion in rewards if goals are met by 2008. [2]

Features

The basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. Conferences of up to five users are supported.

SkypeOut

SkypeOut is a paid feature of the Skype Internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world.

Unlike international long-distance calls made from conventional telephones, which are traditionally rated according to the relative distance between countries, SkypeOut bills all calls according to the level of telecommunications liberalisation of the destination country, the volume of calls made from and to a given country, and access charges such as those to mobile (cell) phones. This rating method is used due to the fact that calls are rated the same regardless of place of origin.

This way, a SkypeOut user will be billed the same for a call placed to a telephone number in London, whether the user is calling from his/her computer in London itself, or from a different country. The Global Rate which is the one used for many countries, including nearly all First World countries, is currently 1.7 euro cents per minute. Credit, which is necessary to use SkypeOut, is usually purchased via credit card, personal check or money order, or online services such as PayPal or Moneybookers. The current deposit is either €10 or €25, which automatically expires after 180 days of inactivity — a timer is reset after each successful SkypeOut connect. In European Union countries, Luxembourg VAT of 15% is added to the charge, which makes the actual prices closer to €0.02 per minute.

SkypeIn

SkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Germany, Sweden, Estonia, Switzerland, Poland and Brazil. (Although France, Germany and Switzerland give SkypeIn numbers only to residents).

Cost is €30 for a twelve-month subscription, or €10 for a three-month subscription. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates.

Skype Voicemail

Skype Voicemail was released on March 10, 2005. This service allows callers to leave voice-mail messages for Skype users who are not online, on another call or otherwise indisposed. This can be purchased separately and is automatically bundled in with SkypeIn.

Skype Chat

Skype supports group chat with an interface similar to IRC.

Skype Video Calling

Skype 2.0 has a Skype Video Calling feature which has been implemented to enable videoconferencing. This feature is only supported when running Windows XP.

Releases

Skype Version 1.2 for Windows was released in March 23, 2005. Its most significant new feature is the provision of centrally-stored contact lists so that a user's contact information is available from any computer that is connected to Skype (in other previous versions, contact information was stored on the local computer).

On 2006-01-05, version 2.0.0.69 of Skype was released.

Versions now exist for Microsoft Windows (Windows 2000, Windows XP and Windows CE (Pocket PC)), Mac OS X and GNU/Linux. The Linux version runs on FreeBSD through its Linux binary compatibility.

Technology

Each Skype user must have the Skype software running on his/her computer. This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary.

The main difference between Skype and other VoIP clients is that it operates on a peer-to-peer model rather than the more traditional server-client model. The Skype user directory is entirely decentralised and distributed among the nodes in the network, which means the network can scale very easily to large sizes (currently just over forty million users) without a complex and costly centralised infrastructure.

Skype also routes calls through other Skype peers on the network, which allows it to traverse Symmetric NATs and firewalls, unlike most other VoIP programs (The two most common VoIP protocols, SIP and H323 are usually UDP and point-to-point, making NAT traversal problematic; see article). This, however, puts an extra burden on those who connect to the Internet without NAT, as their computers and network bandwidth may be used to route the calls of other users. The selection of intermediary computers is fully automatic, with individual users having no option to disable such use of their resources. This fact is not clearly communicated, however, and seems to contradict the license agreement which would limit Skype's utilisation of the user's "processor and bandwidth [to the] purpose of facilitating the communication between [the user] and other Skype Software users" (section 4.1).

The Skype code is closed source and the protocol is proprietary which has raised suspicion and drawn broad criticism from software developers and the VoIP user communities.

The Skype client's application programming interface (API) exposes the network to software developers. The Skype API allows other programs to use the Skype network to get "white pages" information and manage calls.

The Windows user interface was developed in Pascal using Delphi, while the Linux version is written in C++ with Qt and the Mac OS X version is written in Objective-C with Cocoa. [3]

GIPS iLBC CODEC

iLBC (Internet Low Bit-rate Codec) is a free speech codec suitable for most voice communication over IP. The codec is designed for narrowband speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbit/s with an encoding length of 20 ms. The iLBC codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets.

Features

  • Bitrate 13.33 kbit/s (399 bits, packetised in 50 bytes) for the frame size of 30 ms and 15.2 kbit/s (303 bits, packetised in 38 bytes) for the frame size of 20 ms
  • Basic quality higher than G.729A, high robustness to packet loss
  • Computational complexity in a range of G.729A
  • Royalty-free codec

Security

General

Since the Skype code is proprietary and closed source the security of the software cannot be readily established. When run on Microsoft Windows, Skype binds to three ports on the user's computer and directly manipulates Windows XP's built-in firewall to accommodate these network bindings.

Skype's file transfer function does not contain any programmatic interfaces to antivirus products, but Skype claims to have tested its product against antivirus "Shield" products. If the EICAR test file is sent over Skype's file transfer service, every major antivirus product appears to catch the virus and halt its transmission or reception via Skype.

Skype accesses the hard disk several times per minute. This can be verified either by observing the HDD's activity LED or by using a file access monitor such as Filemon. Although those accesses are small, extremely fast and safe in the short term, they can be extremely harmful in the long term. In particular the continuous access pattern does not allow the disk to enter sleep or idle modes while Skype is active, even when offline. This can severely reduce the lifespan of the HDD when Skype is running for a long time. Stronger HDD caching does not seem to improve the situation.

Niklas Zennstrom, co-founder of Skype, has admitted that the current security model would not withstand open-source scrutiny:

Would he make Skype open-source? No - that would make its strong 1024 bit encryption and security vulnerable: "We could do it but only if we re-engineered the way it works and we don't have the time right now."

This would seem to be an admission that Skype relies on security through obscurity.

Confidentiality of Data

Since a Skype connection may be routed through an intermediate peer, 256-bit AES encryption actively encodes the data stream of each call, or file transfer. Skype uses 1536-bit RSA (2048-bit RSA for customers who have purchased any "paid services" such as voicemail) to secure the pairwise negotiation of an AES symmetric session key over an untrusted channel. The proprietary session establishment protocol is efficient and prevents both man-in-the-middle and replay attacks. The Skype server certifies each user's public key at log in.

Integrity/Authenticity of Data

The integrity of the data, i.e. data modified while traveling though peers, even if encrypted, is unknown and undocumented. The mechanism and implementation has been examined in Bernson's report - referenced below.

Authenticity of user identity

Skype provides an uncontrolled registration system for users: registration requires no proof of the identity of the user at all. This works two ways: you can use the system without revealing your identity to other users of the system, but on the other hand you have no guarantees that the person you communicate with is the one he says he is. The down side of this is that it is easy to use the identity of a trusted person and trick a user to reveal information or execute a program sent to him.

Prank program

In September 2005 a prank program was launched online. This unauthorised patch allowed a Skype user to masquerade as another user. The technique was for the joker to put up an attractive profile with a girl’s name and picture, and put that profile into "Skype me" mode. Within minutes generally another user would invariably try calling/chatting. The patch running the whole time would then partner up another call to the first caller, and send messages from the first person to the second, and vice versa. This way both people thought they were talking to a middle user whose profile of course was entirely fake. The patch only supported text messaging.

Usage

SR Consulting surveyed 4 million Skype user profiles in October 2005. They produced some demographic information reported by Mathaba.net and Skype Journal. Some findings:

  • Average age: 29.7 years old.
  • About 46% of Skypers are in Europe, but Brazil and China have the most Skype users of any country, each with 8.1% of the Skype population.
  • Gender information is inconclusive so far. More than half of all users declined to state their sex.

Criticisms

As of July 2005, the line quality varies from excellent (comparable to traditional telephony) to barely usable. The main drawbacks are:

  1. time lag, often around 0.5 seconds, but occasionally up to two or three seconds, apparently caused by distant remote routing or the low bandwidth of either or both parties;
  2. dropout and fizz;
  3. reliance on a network (the Internet) over which there is little or no control of quality of service (QoS). This is the main contributor to its poor performance.

These problems can be minimised by using the service when the network traffic on the Internet is minimal between the ingress and egress to the network. This is however sometimes impossible. The issues are common for all VoIP applications; in fact in restricted networks many of them don't work at all due to firewalls and NAT routers in large private networks from which users attempt to use Skype; while Skype, and other VoIP services are at least able to connect through properly configured third party relay hosts. There are open standards protocols such as SIP and STUN which do the same thing.

A broader criticism leveled at Skype is over its use of a proprietary protocol, instead of an open standard like H.323 or SIP, making it impossible for other providers to interact with the Skype network. There are of course clear business and technical reasons for this, such as protecting the SkypeOut revenue stream.

A design limitation of Skype is, if given access to an unrestricted network connection, Skype clients can become supernodes. These supernodes hold together the peer-peer network and provide data routing for those behind restrictive firewalls. Unfortunately, these supernodes can generate a significant amount of bandwidth—saturating a high speed, 100 Mbit/s connection is not unheard of. For this reason some network providers, such as universities, have banned Skype.

User count and acceptance is often no indicator as to the quality of a service. There may be superior services available whose number of users look poor in comparison with Skype as Skype has been more successful in marketing its service than other pre-existing VoIP telephony services such as VocalTec (established in 1995). The number of users quoted as Skype users are taken from the number of people that have downloaded the software and not necessarily used the service to make voice calls.

SkypeOut rates do not always keep up with the general downward trend in rates charged by conventional telephone companies. For example, in the United Kingdom, the trend is for companies to charge a fixed price per call, for example 3p to 6p for an inland call of unlimited or long duration. With SkypeOut, calls are still charged at a per-minute rate as opposed to a per-call rate, meaning that SkypeOut can be comparatively expensive for inland calls.

The Linux community criticized Skype for not doing any further development for Linux due to the fact that the last release was in October, 2005. The only proof to counteract the criticism is that Skype fixed a Mandriva installation problem on January 6th, 2006. (Release # 1.2.0.21)

Prohibitions and warnings

Legal and other barriers have been erected by companies, government regulators, and school systems. Reasons given include perceived threats to an economic interest, to national or enterprise security, to system reliability.

China 2005

SkypeOut was recently blocked in some regions of mainland China (notably Shenzhen) by the operator China Telecom for undisclosed reasons, believed to relate to SkypeOut's ability to take lucrative international and long distance business away from the People's Republic of China's state controlled telecoms companies.

France 2005

In September 2005, the French Ministry of Research, acting on advice from the general secretariat of national defense, disapproved the use of Skype in public research and higher education; some services are interpreting this decision as an outright ban. The exact reasons for the decision were not given, but computer security professionals point out that:

  • Skype is a proprietary software program using undocumented protocols, and laws prohibit reverse-engineering it;
  • Skype implements some kind of "peer-to-peer" network over client machines, with clients on fast connections becoming major exchange points; since research centers typically have very high speed connections, machines running Skype in those centers may generate very high traffic; some networks were reportedly nearly saturated by Skype traffic;
  • the information flow implemented by Skype is unknown; though encryption is used, it is unknown where traffic goes.

As such, Skype is considered a security hazard for research networks, in which there may be significant intellectual property.


Skype vs traditional phone companies

Phone companies have traditionally charged users a large amount, often proportional to the distance, for long distance calls. Skype, arguably the first major VoIP software, allowed people to talk over the Internet for free. This led to many home users with broadband capability to switch to Skype for placing their calls over the Internet. Skype being secure and encrypted end-to-end, has also attracted large corporations who are beginning to switch from their traditional phone companies for their internal calls. Phone companies were all of a sudden out of favor in the markets which patronized Skype.[citation needed]

Phone companies were all of a sudden out of favor in the markets which patronized Skype.[citation needed]. He "invented" U2’s public image and is still shaping it. Skype being secure and encrypted end-to-end, has also attracted large corporations who are beginning to switch from their traditional phone companies for their internal calls. Since 1982, Anton Corbijn has been photographing U2. This led to many home users with broadband capability to switch to Skype for placing their calls over the Internet. U2 has enjoyed reciprocal influential relationships with artists including REM and Anton Corbijn, as well as exerting influences on others, including the Austrian painter Kave Atefie who dedicated two successful art series ("Like a promise in the year of election" and "Outside it's America") to the work of the Irish band.

Skype, arguably the first major VoIP software, allowed people to talk over the Internet for free. There are several cover versions of U2 songs by Pet Shop Boys, Pearl Jam, Aslan, and The Chimes and musicians such as Cassandra Wilson, Mica Paris and Johnny Cash. Phone companies have traditionally charged users a large amount, often proportional to the distance, for long distance calls. Many musicians have been influenced by the work of U2.

The exact reasons for the decision were not given, but computer security professionals point out that:. author William S. In September 2005, the French Ministry of Research, acting on advice from the general secretariat of national defense, disapproved the use of Skype in public research and higher education; some services are interpreting this decision as an outright ban. U2 also worked together with other artists, including the U.S. SkypeOut was recently blocked in some regions of mainland China (notably Shenzhen) by the operator China Telecom for undisclosed reasons, believed to relate to SkypeOut's ability to take lucrative international and long distance business away from the People's Republic of China's state controlled telecoms companies. Two of the tracks, "Miss Sarajevo" (which got world airplay after its live duet between Bono and Pavarotti was included in the album Pavarotti And Friends) and "Your Blue Room" (a fan favorite, including a vocal track by the band's bassist, Adam Clayton), even made it to their best-of album for 1990-2000. Reasons given include perceived threats to an economic interest, to national or enterprise security, to system reliability. The work is a compilation of film music for nonexistent movies, and a bit of a step back from the usual style of the band, thus the pseudonym "Passengers".

Legal and other barriers have been erected by companies, government regulators, and school systems. 1. (Release # 1.2.0.21). While working under the pseudonym "Passengers," U2 gave producer Brian Eno creative control and cranked out the album Original Soundtracks No. The only proof to counteract the criticism is that Skype fixed a Mandriva installation problem on January 6th, 2006. did a rework of the title track of the movie Mission: Impossible in 1996. The Linux community criticized Skype for not doing any further development for Linux due to the fact that the last release was in October, 2005. The pair also wrote the song "She's A Mystery To Me" for Roy Orbison, which was released on his album Mystery Girl, while Adam Clayton and Larry Mullen Jr.

With SkypeOut, calls are still charged at a per-minute rate as opposed to a per-call rate, meaning that SkypeOut can be comparatively expensive for inland calls. Together with The Edge, Bono wrote the song "GoldenEye" for the James Bond movie of the same name, which was performed by Tina Turner. For example, in the United Kingdom, the trend is for companies to charge a fixed price per call, for example 3p to 6p for an inland call of unlimited or long duration. Bono recorded the song "In a Lifetime" with the Irish band Clannad. SkypeOut rates do not always keep up with the general downward trend in rates charged by conventional telephone companies. U2 has worked with other collaborators; the individual members have also worked in smaller groups together and with outsiders. The number of users quoted as Skype users are taken from the number of people that have downloaded the software and not necessarily used the service to make voice calls. The Edge has also admitted that he writes songs after every show, but only 1 in 10 of these songs on the road will go anywhere, and has expressed longing to get back into a recording studio.

There may be superior services available whose number of users look poor in comparison with Skype as Skype has been more successful in marketing its service than other pre-existing VoIP telephony services such as VocalTec (established in 1995). Since this article has been written, U2 has extended the Vertigo tour to take up a great deal of 2006. User count and acceptance is often no indicator as to the quality of a service. Thus, they consider Pop at least a partial artistic failure, despite over 7 million in sales. For this reason some network providers, such as universities, have banned Skype. Bono has said that the biggest mistake the band has ever made was letting their manager book the PopMart tour, as it meant they had to rush to finish the Pop album. Unfortunately, these supernodes can generate a significant amount of bandwidth—saturating a high speed, 100 Mbit/s connection is not unheard of. Considering recent comments from the members of the band, this now seems more likely than them rushing to get the remains of the How to Dismantle... sessions finished.

These supernodes hold together the peer-peer network and provide data routing for those behind restrictive firewalls. There have also been talks of U2 re-recording their 1997 album, Pop for a tenth anniversary. A design limitation of Skype is, if given access to an unrestricted network connection, Skype clients can become supernodes. The album was released only a year and half after their groundbreaking album Achtung Baby. There are of course clear business and technical reasons for this, such as protecting the SkypeOut revenue stream. In 1993, during a break in the massive Zoo TV Tour, U2 recorded what was to be Zooropa. A broader criticism leveled at Skype is over its use of a proprietary protocol, instead of an open standard like H.323 or SIP, making it impossible for other providers to interact with the Skype network. In the January 2006 edition of Q magazine, Bono said that the band were working on a new album for 2006.

There are open standards protocols such as SIP and STUN which do the same thing. Most likely a new record will surface in 2007, but 2006 cannot be ruled out entirely. The issues are common for all VoIP applications; in fact in restricted networks many of them don't work at all due to firewalls and NAT routers in large private networks from which users attempt to use Skype; while Skype, and other VoIP services are at least able to connect through properly configured third party relay hosts. The Vertigo tour kicked off in San Diego on 28 March and is expected to go well into 2006, so there aren't current plans to go into the studio to record. This is however sometimes impossible. According to Bono there are 24 songs that came out of sessions, of which the band took 11 for their subsequent record. These problems can be minimised by using the service when the network traffic on the Internet is minimal between the ingress and egress to the network. In mid-2005, a source (Anti-Music) reported that U2 have plans for a new album and are keen to record more.

The main drawbacks are:. On December 18, 2005, Time magazine awarded its prestigious "Person of the Year" honor to Bono as well as philanthropists Bill and Melinda Gates [3]. As of July 2005, the line quality varies from excellent (comparable to traditional telephony) to barely usable. U2 was featured on the album as part of Blige's remake of U2's "One". Some findings:. Blige released her ninth studio album "The Breakthrough". They produced some demographic information reported by Mathaba.net and Skype Journal. On December 8, U2 was awarded with 5 Grammy nominations, including 'Album of the Year', and 'Song of the Year' for "Sometimes You Can't Make It On Your Own." On December 20, Mary J.

The Vertigo Tour European leg climaxed at the Estádio José Alvalade XXI in Lisbon on August 15 after the band received the country's most prestigious honour, the Order of Liberty from Portugal's President Jorge Sampaio regarding the band's hugely influential work for action in Africa and across the world concerning extreme poverty.

In Belgium, France and Austria the tickets were sold within 60 minutes.

The patch only supported text messaging. U2 have smashed Irish box office records with ticket sales for their 2005 Croke Park, Dublin concerts, after more than 240,000 tickets were sold in record time. This way both people thought they were talking to a middle user whose profile of course was entirely fake. The DVD marks their third live film since their 2001 Elevation Tour. The patch running the whole time would then partner up another call to the first caller, and send messages from the first person to the second, and vice versa. Their featured stop in Chicago, Illinois was filmed over two nights in May, 2005 for the live DVD U2 - Vertigo 2005 // Live From Chicago. Within minutes generally another user would invariably try calling/chatting. The band then returned to the United States and finished up on December 19 in Portland, Oregon.

They played in a number of venues including Paris, Amsterdam, London, Dublin, Rome and Oslo. This unauthorised patch allowed a Skype user to masquerade as another user. The second leg was a European stadium tour, which started on June 10 in Brussels and finished on August 14 in Lisbon. In September 2005 a prank program was launched online. The band performed well-known hits, songs from the current album, and early rarities. The down side of this is that it is easy to use the identity of a trusted person and trick a user to reveal information or execute a program sent to him. The first leg started off in March in San Diego, California and finished in May in Boston, Massachusetts.

This works two ways: you can use the system without revealing your identity to other users of the system, but on the other hand you have no guarantees that the person you communicate with is the one he says he is. The first leg of the Vertigo Tour began in the United States, with the band performing 26 sold-out shows. Skype provides an uncontrolled registration system for users: registration requires no proof of the identity of the user at all. The song appears to be so popular, many fans are citing it as one of their top 10 all-time favourite U2 tracks, saying it's U2's best songwriting in years, harking back to the days of sonic experimentation witnessed in 1991's "Achtung Baby". The mechanism and implementation has been examined in Bernson's report - referenced below. Some say it should have been included on 'How to Dismantle an Atomic Bomb' [it was left off, along with 'Fast Cars', which surfaced as a bonus track in some countries, to prevent the album from running too long over an hour] whereas others feel the track should be kept for U2's next album. data modified while traveling though peers, even if encrypted, is unknown and undocumented. The track, in its current form floating around on the internet, is of less than standard audio quality but has still got the ball rolling on many a debate.

The integrity of the data, i.e. Though it is still unknown where this copy of the album (which at the time of writing is still the only declared CD [let alone copy of 'How To...'] in the public domain to have the track) came from, the track caused mass hysteria throughout the U2 fan community! Numerous websites hosted the track, touting it as a yet unreleased B-side after Bono told the same fan who received the 'Special copy' weeks after meeting the singer to "Watch out for Mercy" as it was one of his favourite songs from the sessions and is the "Best B-side ever recorded." *not verbatim. The Skype server certifies each user's public key at log in. In late 2004, "Mercy", an unreleased track taken from the 'How to Dismantle an Atomic Bomb' sessions, surfaced on the internet thanks to a fan who had been given a copy of the album containing the extra track. The proprietary session establishment protocol is efficient and prevents both man-in-the-middle and replay attacks. They were inducted by their good friend Bruce Springsteen. Skype uses 1536-bit RSA (2048-bit RSA for customers who have purchased any "paid services" such as voicemail) to secure the pairwise negotiation of an AES symmetric session key over an untrusted channel. On March 14, 2005, U2 was inducted into the Rock and Roll Hall of Fame in their first year of eligibility.

Since a Skype connection may be routed through an intermediate peer, 256-bit AES encryption actively encodes the data stream of each call, or file transfer. In April 2004, Rolling Stone magazine placed U2 in its 50 "greatest rock & roll artists of all time". This would seem to be an admission that Skype relies on security through obscurity. The DVD carries a video of an exclusive live performance of "Sometimes You Can't Make It On Your Own" from the band's Dublin studio, and a Trent Reznor remix of "Vertigo.". Would he make Skype open-source? No - that would make its strong 1024 bit encryption and security vulnerable: "We could do it but only if we re-engineered the way it works and we don't have the time right now.". The single will be available on two CD formats and a DVD single. Niklas Zennstrom, co-founder of Skype, has admitted that the current security model would not withstand open-source scrutiny:. The performance is a Jacknife Lee remix of "Ave Maria" sung by Bono with Luciano Pavarotti.The B-Side of the single also includes a remix of the hit "Vertigo" and a Jacknife Lee remix of "Fast Cars." Fast Cars is an album track available only on the UK and Japan versions and American deluxe editions of Atomic Bomb.

Stronger HDD caching does not seem to improve the situation. In Europe, the next single released from the album - "Sometimes You Can't Make It On Your Own" - once again featured a Bono/Pavarotti performance on the B-side. This can severely reduce the lifespan of the HDD when Skype is running for a long time. Owners of the U2 Edition iPod were able to purchase this collection at a discount. In particular the continuous access pattern does not allow the disk to enter sleep or idle modes while Skype is active, even when offline. The digital box set features each U2 album in its entirety, as well as every single and B-side ever released, rare live sets, and previously unreleased songs from recording sessions of All That You Can't Leave Behind and How to Dismantle an Atomic Bomb. Although those accesses are small, extremely fast and safe in the short term, they can be extremely harmful in the long term. The partnership also led Apple's iTunes Music Store to feature a collection known as The Complete U2.

This can be verified either by observing the HDD's activity LED or by using a file access monitor such as Filemon. The band also licensed a special version of the iPod with a U2 design (black faceplate with red click wheel, echoing the color scheme for the new album) and facsimiles of the bandmembers' signatures etched on the back plate. Skype accesses the hard disk several times per minute. This move shocked some fans who remember U2's previous staunch refusal to get involved in any product promotion. If the EICAR test file is sent over Skype's file transfer service, every major antivirus product appears to catch the virus and halt its transmission or reception via Skype. In another first, the band entered an extensive cross-promotion campaign with Apple Computer: the band allowed the single "Vertigo" to be used in a widely aired television commercial for the iPod music player -- though the band did not receive any royalties for the use of the song, due to the commercial the song was well known even before the release of the album. Skype's file transfer function does not contain any programmatic interfaces to antivirus products, but Skype claims to have tested its product against antivirus "Shield" products. They then played a free concert at a park beneath the Brooklyn Bridge, attracting over 30,000 fans who had learned of the show on various U2 fan websites.

When run on Microsoft Windows, Skype binds to three ports on the user's computer and directly manipulates Windows XP's built-in firewall to accommodate these network bindings. The band also made a video for the second North American single, "All Because Of You", while riding on a flatbed truck through the streets of Manhattan on November 22. Since the Skype code is proprietary and closed source the security of the software cannot be readily established. They made appearances on TV shows like CD:UK and Friday Night with Jonathan Ross in Britain and Saturday Night Live in America. The iLBC codec enables graceful speech quality degradation in the case of lost frames, which occurs in connection with lost or delayed IP packets. U2 promoted How to Dismantle an Atomic Bomb heavily. The codec is designed for narrowband speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbit/s with an encoding length of 20 ms. This was a record for the band, nearly doubling the first-week sales of All That You Can't Leave Behind in the US.

iLBC (Internet Low Bit-rate Codec) is a free speech codec suitable for most voice communication over IP. It sold 840,000 units in the United States in its first week. [3]. The album debuted at #1 in 32 countries, including the United States, Canada, the United Kingdom and the band's native Ireland. The Windows user interface was developed in Pascal using Delphi, while the Linux version is written in C++ with Qt and the Mac OS X version is written in Objective-C with Cocoa. The album, titled How to Dismantle an Atomic Bomb, was released on November 22 in much of the world and November 23 in the United States. The Skype API allows other programs to use the Skype network to get "white pages" information and manage calls. The song received extensive airplay in the first week after its release and became an international hit.

The Skype client's application programming interface (API) exposes the network to software developers. No such pre-release of the album occurred, however, and the first single from the album, titled "Vertigo", was released for airplay on September 24, 2004. The Skype code is closed source and the protocol is proprietary which has raised suspicion and drawn broad criticism from software developers and the VoIP user communities. Shortly thereafter, Bono stated that, should the album appear on P2P networks, it would be released immediately via iTunes and be in stores within a month. This fact is not clearly communicated, however, and seems to contradict the license agreement which would limit Skype's utilisation of the user's "processor and bandwidth [to the] purpose of facilitating the communication between [the user] and other Skype Software users" (section 4.1). A rough-cut of the band's follow-up album was stolen in Nice, France, in July 2004 [2]. The selection of intermediary computers is fully automatic, with individual users having no option to disable such use of their resources. I especially like the bassline." The track went to the top of the UK singles charts in February 2004 and also went top 5 in Ireland and top ten in Australia.

This, however, puts an extra burden on those who connect to the Internet without NAT, as their computers and network bandwidth may be used to route the calls of other users. Adam Clayton said of the track: "It's a good beat and you can dance to it. Skype also routes calls through other Skype peers on the network, which allows it to traverse Symmetric NATs and firewalls, unlike most other VoIP programs (The two most common VoIP protocols, SIP and H323 are usually UDP and point-to-point, making NAT traversal problematic; see article). U2. The Skype user directory is entirely decentralised and distributed among the nodes in the network, which means the network can scale very easily to large sizes (currently just over forty million users) without a complex and costly centralised infrastructure. All four members of U2 had to clear the track, which was released under the title of LMC vs. The main difference between Skype and other VoIP clients is that it operates on a peer-to-peer model rather than the more traditional server-client model. Dance artists LMC sampled "With or Without You" for their track "Take Me To The Clouds Above" which also features lyrics from "How Will I Know" by Whitney Houston.

This software is currently available free of charge and can be downloaded from the company website, but the software is proprietary. In late 2002, U2 released part two of its greatest hits collection, The Best of 1990-2000. Each Skype user must have the Skype software running on his/her computer. Bono continued his campaigns for debt and HIV/AIDS relief throughout the summer of 2002. The Linux version runs on FreeBSD through its Linux binary compatibility. All That You Can't Leave Behind went on to receive four more Grammy Awards. Versions now exist for Microsoft Windows (Windows 2000, Windows XP and Windows CE (Pocket PC)), Mac OS X and GNU/Linux. Bono then opened his jacket, which he had worn throughout the Elevation Tour, to reveal the American flag printed as the lining, an image that was widely reproduced in the media.

On 2006-01-05, version 2.0.0.69 of Skype was released. The highlight was an emotional performance of "Where the Streets Have No Name" in which the names of the victims of the September 11, 2001 attacks were projected onto a pair of backdrops, scrolling up towards the sky; at the end of the song the backdrops were released, descending to the ground in a gentle revisiting of the Twin Towers' fall. Its most significant new feature is the provision of centrally-stored contact lists so that a user's contact information is available from any computer that is connected to Skype (in other previous versions, contact information was stored on the local computer). After the Elevation Tour ended in late 2001, the culmination of U2's critical resurrection came when the band performed a well-received three-song set in New Orleans, Louisiana during halftime of Super Bowl XXXVI. Skype Version 1.2 for Windows was released in March 23, 2005. Following such an accomplished album, and a hugely successful tour, many fans felt that U2 had been successful in "re-applying for the job of the biggest band in the world," an application Bono had made a year earlier. This feature is only supported when running Windows XP. The tour ended up as the top concert draw in North America in 2001.

Skype 2.0 has a Skype Video Calling feature which has been implemented to enable videoconferencing. The terrorist attacks of September 11, 2001 nearly led U2 to cancel the last third of the tour but they decided to continue nonetheless; the new album's "Walk On" gained added resonance. Skype supports group chat with an interface similar to IRC. The Elevation Tour saw the band performing in a scaled-down setting, returning to arenas after nearly a decade of stadium productions, with a heart-shaped stage and ramp permitting greater proximity to the audience. This can be purchased separately and is automatically bundled in with SkypeIn. U2 followed that release with a major tour in the spring of 2001, the Elevation Tour. This service allows callers to leave voice-mail messages for Skype users who are not online, on another call or otherwise indisposed. 1 in 22 countries and spawned a world-wide hit single, "Beautiful Day", which also earned three Grammy Awards.

Skype Voicemail was released on March 10, 2005. It debuted at No. For example, someone who does business in both San Francisco and Helsinki could create a local telephone number in each city, and callers from those locations would pay cheap or free local rates. All That You Can't Leave Behind, released in late October of 2000, was received widely as U2's return to grace, and was considered by many to be U2's "third masterpiece", following The Joshua Tree and Achtung Baby. Users can have multiple SkypeIn phone numbers bound to the same account (a separate subscription is required for each). The song eventually appeared on the soundtrack to The Million Dollar Hotel, a movie based on a story written by Bono. Cost is €30 for a twelve-month subscription, or €10 for a three-month subscription. During these sessions, the band collaborated with author Salman Rushdie, who wrote the lyrics to a song called "The Ground Beneath Her Feet", taken from his book of the same name.

(Although France, Germany and Switzerland give SkypeIn numbers only to residents). After the overwhelming extravagance of the Popmart Tour, critics and music industry insiders felt that U2 was trying to return to the days of The Joshua Tree in order to keep its audience of loyal fans. Beta released on March 10, 2005, SkypeIn permits users to subscribe to numbers in UK, USA, France, Hong Kong, Denmark, Finland, Germany, Sweden, Estonia, Switzerland, Poland and Brazil. U2 went back into the studio in early 1999, yet again with Brian Eno and Daniel Lanois producing. SkypeIn allows Skype users to receive calls on their computers dialed by regular phone subscribers to regular phone numbers. In late 1998, U2 released its first greatest hits compilation, The Best of 1980-1990. In European Union countries, Luxembourg VAT of 15% is added to the charge, which makes the actual prices closer to €0.02 per minute. Also that year, U2 performed on an Irish TV fundraiser for victims of the Omagh, Northern Ireland bombing which killed 28 and injured hundreds earlier in the year.

The current deposit is either €10 or €25, which automatically expires after 180 days of inactivity — a timer is reset after each successful SkypeOut connect. The band played a brief concert in Belfast in May of 1998, three days before the public voted in favour of the Northern Ireland Peace Accord. Credit, which is necessary to use SkypeOut, is usually purchased via credit card, personal check or money order, or online services such as PayPal or Moneybookers. The shows were also intended to be shining a mirror back onto the world, taking all the subtle advertising and messages we are exposed to every day and blowing them up so they were visible to the world, best shown in the famous picture of Bono (dressed as The Fly) with the message "WATCH MORE TV" written next to it. The Global Rate which is the one used for many countries, including nearly all First World countries, is currently 1.7 euro cents per minute. The Popmart Tour and Zoo TV Tour was intended to send a sarcastic message to all those accusing U2 of commercialism. This way, a SkypeOut user will be billed the same for a call placed to a telephone number in London, whether the user is calling from his/her computer in London itself, or from a different country. The Popmart Tour was the second-highest grossing tour of 1997 (behind the Rolling Stones' Bridges to Babylon Tour) with revenues of just under $80 million, but it cost more than $100 million to produce.

This rating method is used due to the fact that calls are rated the same regardless of place of origin. One of the stops was in Sarajevo, where they were the first major group to perform after the war there. Unlike international long-distance calls made from conventional telephones, which are traditionally rated according to the relative distance between countries, SkypeOut bills all calls according to the level of telecommunications liberalisation of the destination country, the volume of calls made from and to a given country, and access charges such as those to mobile (cell) phones. It was to be U2's most colorful show to date. SkypeOut is a paid feature of the Skype Internet telephony service, which allows Skype users to call virtually any non-computer-based landline or mobile telephone in the world. The show hit the road in April, 1997; the set included a 100-foot tall golden yellow arch, a large 150 foot long video screen, and a 35 foot tall mirrorball lemon. Conferences of up to five users are supported. With the Popmart Tour, U2, once again continued the Zoo TV theme of decadence.

The basic computer-to-computer service allows users to speak, to send instant messages or to send files to one another from their computers via the Internet at no cost. It is not surprising that the tracks from Pop picked for U2's second greatest hits album – "Gone", "Discothèque", and "Staring at the Sun" – were all remixed for inclusion on that album. . The band has admitted they were hurried into completing the album and say that a number of tracks on the album were not finished as well they would have liked. [2]. One of the main problems the band had when the recording the album was the time constraint placed upon them by their impending tour. In September 2005, in a deal generally criticised by many as overpriced [1], eBay acquired the company for $US 2.6 billion in cash and stock, plus an additional 1.5 billion in rewards if goals are met by 2008. Rolling Stone even went so far as claiming U2 had "defied the odds and made some of the greatest music of their lives." However, audiences and fans felt that the music industry had exceeded the limits of tolerance in promoting Pop, and the album was seen as something of a disappointment by many.

Skype users can speak to other Skype users for free, call traditional telephone numbers for a fee (SkypeOut), receive calls from traditional phones for a fee (SkypeIn), and receive voicemail messages for a fee. The album debuted at #1 in 28 countries, and earned U2 mainly positive reviews. The system has a reputation for working across different types of network connections (including firewalls and NAT) because voice packets are routed by the combined users of the free desktop software application. Pop was released in March of 1997. The Skype Group is headquartered in Luxembourg with offices also in London and Tallinn. This gave the album a techno/disco feel. Skype (IPA pronunciation: /skaɪp/, rhymes with type) is a proprietary peer-to-peer Internet telephony (VoIP) network, founded by Niklas Zennström and Janus Friis, the creators of KaZaA and competing against established open VoIP protocols like SIP or H.323. U2 were once again attempting to change their musical direction, this time the band were experimenting with heavy post production of their music, utilizing tape loops, programming and sampling.


. The recording of this album was fraught with difficulty. the information flow implemented by Skype is unknown; though encryption is used, it is unknown where traffic goes. In early 1996, U2 began work on their next record. Skype implements some kind of "peer-to-peer" network over client machines, with clients on fast connections becoming major exchange points; since research centers typically have very high speed connections, machines running Skype in those centers may generate very high traffic; some networks were reportedly nearly saturated by Skype traffic;. The album, including a collaboration with Luciano Pavarotti, "Miss Sarajevo", was not largely noticed in the industry, and received little attention from the critics and public alike. Skype is a proprietary software program using undocumented protocols, and laws prohibit reverse-engineering it;. 1
.

This is the main contributor to its poor performance. After some time off - and a few side projects (the Batman Forever and Mission: Impossible soundtracks) - the band returned under the radar in 1995 with Brian Eno under the moniker "Passengers", and released an experimental album called Original Soundtracks No. reliance on a network (the Internet) over which there is little or no control of quality of service (QoS). In particular, the tracks Zooropa, Stay (Faraway, So Close!) and, maybe most of all, The Wanderer, a duet with Johnny Cash, proved influential in winning the admiration of new fans. dropout and fizz;. The Zooropa album was, like Achtung Baby before it, popular among people who had never been fans of U2 before, further expanding the fanbase and hugely increasing the band's ability to remain popular into the 1990s and beyond. time lag, often around 0.5 seconds, but occasionally up to two or three seconds, apparently caused by distant remote routing or the low bandwidth of either or both parties;. Zooropa was an even greater departure from the style of their earlier recordings, incorporating techno style and other electronic effects.

More than half of all users declined to state their sex. The album was intended as an additional EP to Achtung Baby, but soon Zooropa expanded into a full-fledged LP and was released in July of 1993. Gender information is inconclusive so far. Following the same theme, U2 went back into the studio to record their next release during a break in the Zoo TV Tour. About 46% of Skypers are in Europe, but Brazil and China have the most Skype users of any country, each with 8.1% of the Skype population. European leg link-ups to war-torn Sarajevo caused further controversy. Average age: 29.7 years old. Some missed the point of the tour and thought that U2 had "lost it," and that Bono had become an egomaniac.

February 3, 2006: Skype becomes fully integrated with popular online message board Bebo allowing registered users to call and IM eachother directly from their profiles. The tour was, among other things, U2's attempt at mocking the excesses of rock and roll by appearing to embrace greed and decadence - at times, even away from the stage. January 19, 2006: Skype 2.0 official release. The multimedia event known as the Zoo TV Tour masterfully confused audiences with hundreds of video screens, upside-down flying Trabant cars, mock transmission towers, satellite TV links, subliminal text messages, and over-the-top stage characters such as "The Fly", "Mirror-ball Man" and "Mister MacPhisto". January 6, 2006: Skype 2.0 general release is announced. In early 1992, U2 began its first American tour in more than four years. December 1, 2005: Skype launches Skype 2.0 in beta for Windows, a major new feature is videotelephony to other Skype users [4]. New fans were perhaps most drawn in by the song "Mysterious Ways".

October 18, 2005: eBay completes purchase of Skype (announcement). The group's fanbase was therefore expanded significantly by this release. September 12, 2005: eBay announces purchase of Skype (see GAMEY). The album was enthusiastically received by fans and critics alike, with Rolling Stone magazine declaring that U2 had "proven that the same penchant for epic musical and verbal gestures that leads many artists to self-parody can, in more inspired hands, fuel the unforgettable fire that defines great rock & roll." What was often said at the time was that Achtung Baby introduced a legion of new U2 fans, people who had heard the group for many years but never really liked them or bought their records before. September 2005: SkypeOut Banned in South China. In November of 1991, U2 released the heavily experimental and distorted Achtung Baby. August 31, 2005: Skype launches the new "1.4 beta" containing improved sound and call forwarding. The original sessions did not go well, but following the inspirational completion of the hit song 'One,' the band eventually emerged from the studio with renewed energy and a new album under its belt.

June 19, 2005: Ten billion minutes of voice conversation served. After taking some time off, the band met in East Berlin in autumn of 1990 to begin work on their next studio album, again with Brian Eno and Daniel Lanois producing. May 18, 2005: Three million online at once. Perhaps feeling that U2 was somewhat stagnating, Bono announced during a December 30, 1989 concert in Dublin that it was time "to go away and dream it all up again.". April 15, 2005: Downloaded more than 100 million times. King), which visited Australia, New Zealand, and Japan, but avoided the US and most of Europe. March 11, 2005: Software has been downloaded 84 million times and 5.98 billion talk minutes served. U2 went on the Lovetown Tour (with special guest B.B.

March 11, 2005: Skype press release reports 1 million Skype-out users and 29 million registered users. Despite a positive reception from fans, Rattle and Hum received mixed-to-negative reviews from both film and music critics. March 10, 2005: SkypeIn Public Beta starts. Amongst the songs performed live that made it to the album were Helter Skelter (see above), a cover version of Bob Dylan's famous song All Along The Watchtower. February 14, 2005: First reached 2 million online. King, and sang about blues great Billie Holiday. October 20, 2004: First time 1 million Skype users are online at once. That album became a tribute to American music, which the band recorded part of at the legendary Sun Studios in Memphis (along with The Point Depot, Dublin, Ireland), performed with Bob Dylan and B.B.

July 27, 2004: Release of Version 1.0 for Windows. The band began to film and record various shows from the tour for the documentary and double album Rattle and Hum in 1988 and released on video in 1989. June 27, 2004: SkypeOut credits first available for purchase on Skype website. The band also covered The Beatles' "Helter Skelter", declaring "This is a song Charles Manson stole from the Beatles; we're stealin' it back.". Credits by voucher only. At Wembley Stadium in London, in 1987, U2 sang a haunting version of The Beatles' "Help!" - dedicating it to those in the audience who were dreading another five years of the recently re-elected Prime Minister, Margaret Thatcher. June 15, 2004: Beta release of version 0.98.0.28 with first support for SkypeOut. Bono and U2 were still able to seize the moment.

August 29, 2003: First public beta version released. The Joshua Tree Tour sold out stadiums around the world, the first time the band had consistently played venues of that size . April 23, 2003: Skype.com and Skype.net domain names registered. U2 was the fourth rock band to be featured on the cover of Time magazine (following The Beatles, The Band, and The Who), who declared that U2 was "Rock's Hottest Ticket". Royalty-free codec. The singles "With or Without You" and "I Still Haven't Found What I'm Looking For" also quickly went to #1 in the U.S., with "Where the Streets Have No Name" being another heavily played track. Computational complexity in a range of G.729A. The album debuted at #1 in the U.K., quickly reached #1 in the U.S., and would go on to win the Grammy Award for Album of the Year.

Basic quality higher than G.729A, high robustness to packet loss. In 1987, U2 released The Joshua Tree. Bitrate 13.33 kbit/s (399 bits, packetised in 50 bytes) for the frame size of 30 ms and 15.2 kbit/s (303 bits, packetised in 38 bytes) for the frame size of 20 ms. performed to sold-out arenas and stadiums, and helped Amnesty International triple its membership in the process. This 6-show tour across the U.S. U2 went on to a headlining spot on 1986's A Conspiracy of Hope Tour for Amnesty International.

In 1985 Rolling Stone magazine called U2 the "Band of the 80s", saying that "for a growing number of rock-and-roll fans, U2 has become the band that matters most, maybe even the only band that matters.". Somewhat ironically, the Live Aid version of "Bad" has become something of a legend in rock circles, and was an indication of the personal connection that Bono could make with audiences. After the concert, the other band members demanded he leave U2, Bono instead took a few weeks off to think about his role in the band, and was welcomed back with open arms. admitted that the rest of the band had considered leaving the stage as he was performing.

Larry Mullen Jr. The other band members were upset with Bono for spending the time they had planned for playing "Pride (In the Name of Love)", and Bono was convinced he had squandered a chance for promoting the band to a greater audience. U2 were not expected to be one of the main draws for the event, but the band provided the show with one of its most memorable moments, a relentless 13-minute version of "Bad" in which Bono leapt off the stage to dance with a fan. The Live Aid concert at Wembley Stadium for Ethiopian famine relief in July 1985 was seen by more than a billion people worldwide.

Miles Davis is reputed to have asked the album to be played while on his deathbed. The tour itself became the first time U2 extensively played in indoor arenas. During the Unforgettable Fire Tour to support the new album, Bono took to wrapping his microphone cable around his arm in imitation of a junkie looking for a vein. The centrepiece of the album is "Bad", a long, experimental song which, while never released as a single, provided the album's defining moment: a cathartic exploration on the theme of heroin dependency - a problem particularly prevalent in the Dublin of the mid-1980s.

The album's release coincided with a photo exhibit at the Chicago Peace Museum featuring images of the aftermath of the Hiroshima and Nagasaki bombings; Bono would later contribute a poem entitled "Dreams in Box" to the museum's archives. Songs include "Indian Summer Sky", a social commentary on the prison-like atmosphere of city living in a world of natural forces, and "MLK", a second song honoring Martin Luther King, Jr. However, the material, although less overtly so, remained political. The album represented a turning point in the band's career, as Bono's lyrics became more complex, subtle and experimental, the Edge's guitar explored new sonic landscapes, and the rhythm section got looser and funkier.

Top 5 and the US Top 50. "Pride" became the first single from the album, cracking the U.K. The album featured the tribute to civil rights leader Martin Luther King, Jr., "Pride (In the Name of Love)". The experimental The Unforgettable Fire (named after a series of paintings made by survivors of the atomic bombs at Hiroshima and Nagasaki) followed in 1984.

The band began their fourth studio album with Brian Eno and Daniel Lanois producing. The band recorded the Under a Blood Red Sky EP on this tour and a live video was also released, both of which received radio and MTV play and helped expand the band's audience. on their subsequent War Tour. For the first time, the band began performing to sold-out concerts in mainland Europe and the U.S.

MTV put the "New Year's Day" video into heavy rotation, which helped introduce U2 to the American audience. charts. charts and nearly cracking the Top 50 on the U.S. The album's first single, "New Year's Day", was U2's first international hit single, reaching the #10 position on the U.K.

His anger and passion were palpable as he shouted: "Fuck the 'revolution'!". This song is Sunday Bloody Sunday." Furthermore, as captured in the concert film U2: Rattle and Hum, during the performance of the song on November 9, 1987, the day after the IRA bombing in Enniskillen, County Fermanagh, Northern Ireland, in which 11 people were killed during a Remembrance Day service, Bono bluntly denounced the violence in Ireland and the Irish expatriates who supported it. When some Irish-Americans tried to misrepresent the song as a rallying call for the Provisional IRA Bono responded with what became one of his most recognizable phrases in concerts, notably the performance on the live EP Under a Blood Red Sky - "this song is not a rebel song. The ability to use such a range of images, taking a song initially about sectarian anger, and turn it into a call for Christians to unite and claim the victory over death and evil that Christ achieved in the resurrection, showed the depth of the band's songwriting ability.

The song starts off by expressing the anger felt in Ireland over Bloody Sunday incident of 1972, but in successive stanzas moves through different imagery that disown that anger and place the song in a religious context, using imagery from Matthew 10:35 ("mother's children; brothers, sisters torn apart"), and a twist on 1 Corinthians 15:32 ("we eat and drink while tomorrow they die") before finishing off with a call for Christians to stop fighting each other and "claim the victory Jesus won, on a Sunday bloody Sunday". The album included the song "Sunday Bloody Sunday" , which dealt with the troubles in Northern Ireland. In 1983, U2 returned with apparently a newfound sense of direction and the release of their third album, War. Whiteley & Maynard, ISBN 1561012238).

(In recent years a book of sermons based on U2 songs has been published: "Get Up Off Your Knees" ed. While the Bible has remained a major source of inspiration for Bono’s lyric writing, October is U2’s only overt Christian rock album… and is generally held to be among their least successful work. After nearly throwing in the towel on U2, they decided it was possible to reconcile the two by continuing to make music without compromising their personal beliefs. The three band members joined a religious group in Dublin called "Shalom", which led all three to question the relationship between the Christian faith and the rock and roll lifestyle.

Bono, the Edge and Larry were committed Christians and made little effort to hide that fact. Fans and music critics quickly made note of the band's spiritual lyrics. The band's second album, October, was released in 1981. These live shows helped establish U2 as one of the most exciting live bands in the UK, as critics noted that Bono was a very "charismatic" and "passionate" showman.

Boy's release was followed by U2's first tour beyond Ireland and the United Kingdom. He can also be seen as a would-be band member in the Alan Parker feature "The Committments"). (The same boy, three years older, would be employed for artwork on U2's War album. Lord of the Flies also inspired the famous album art which featured photographs of a disheveled boy, naked from the waist up, sometimes wearing war paint or an army helmet.

One song, “Shadows and Tall Trees,” gives a nod to William Golding’s novel Lord of the Flies, which was an inspiration for the album. Despite Bono’s unfocused, improvised lyrics, Boy has a definite theme – a vulnerable, painfully honest examination of adolescence touching on fear over sex, identity confusion, death and uncontrollable mood swings. It was met with critical praise and is considered one of the better debuts in rock history. U2 released Boy the following October.

Island Records signed the band in March of 1980. They performed "I Will Follow" and "Twilight" and engaged in an interview. It aired on June 4, 1981. U2 made their first appearance on US television on The Tomorrow Show hosted by Tom Snyder.

In December of that year, U2 travelled to London for its first shows outside of Ireland, but failed to get much attention from foreign audiences and critics. It topped the Irish charts. Now a four-piece with a local fan base in place, U2 released their first single in September of 1979, U2-3. In May, Paul McGuinness became U2's manager.

Dik walked offstage halfway through the set and later joined the Virgin Prunes, a fellow Dublin band. The Hype performed a farewell show for Dik at the Community Centre in Howth. Dik Evans announced his departure in March 1978. However, in an interview with Larry King, Bono is quoted as saying "I don't actually like the name U2," and "I honestly never thought of it as 'you too'." Others feel that U2 derived its name from the Irish Unemployment form.

They believe that the audience is part of their music and the concert and that "you too" (U2) are participating in the music. Some suggest the meaning of the name "U2" is based on their philosophy. The Dublin punk rock guru Steve Averill (better known as Steve Rapid of the The Radiators From Space) suggested that "The Hype stinks, at least as a name." Someone offered "What about U2? It's the name of a spyplane and a submarine, and it's got an endearing inclusivity about it." [1]. Hayden was impressed enough with the band that he gave them studio time to record their first demo.

One of the judges for the show happened to be CBS Records' Jackie Hayden; they won the contest, earning a £500 prize. The band performed with their new name at a talent show in Limerick, Ireland on 17 March 1978. After 18 months of rehearsals, Feedback changed their name to The Hype. There are also other theories on the origins of The Edge's nickname:.

Bono also thought that it was an accurate description of his head, as it had a straight edge. The sign has since been changed to read "Bonavox." The Edge got his name from Bono, who thought he was always on the edge of things, assessing what was going on. Hewson was nicknamed Bono Vox (allegedly meaning 'good voice' in Latin, though a more accurate translation would in fact be vox bona), after a hearing aid company's advertising sign on the corner of Dame Street and South Great Georges Street in Dublin's city centre (a different theory says he was nicknamed after a hearing aid shop by his friend Gavin Friday because he sang so loudly he seemed to be singing for the deaf). Both Martin and McCormick were out of the core group within a few weeks, with McCormick dismissed by Adam Clayton with the excuse that he was too young to play at the bars in which U2 would be booked.

Although known as an Irish band, two members —The Edge and Adam Clayton— are actually British by birth. Soon after, the group settled on the name Feedback. Known for about a day as "The Larry Mullen Band," Larry's group featured Mullen on drums, Adam Clayton on bass guitar, Paul Hewson (Bono) on vocals, Dave Evans (The Edge) on guitar, his brother Dik Evans on guitar, and Mullen's friends Ivan McCormick and Peter Martin on guitar. The response that followed that note resulted in seven boys attending the initial practice in Larry's kitchen.

The band is also very politically active in human rights causes, such as the Make Poverty History campaign as well as the campaign spearheaded by Bono, DATA (Debt, AIDS, Trade in Africa). and are widely considered as one of the most successful groups of all time. According to the RIAA, they have sold approximately 50.5 million albums in the U.S., had six #1 albums in the U.S. U2 have been one of the most popular rock/vocal bands in the world since the 1980s.

He lived on the 'edge' of their imaginary world called 'Lypton Village'. Bono once claimed on Irish radio that the name was derived from the shape Edge made when playing guitar. The name is due to the crispness of his playing, the "edges" it has. He is named after a hardware shop in Fairview, Dublin, outside of which he used to catch the bus home.
