(once capitalized as "'''KaZaA'''", but now usually left as "'''Kazaa'''") is a controversial
Peer-to-peer File Sharing application using the
FastTrack Protocol . It is commonly used to exchange
MP3 music files over the Internet. It is also increasingly used to exchange movie files. The official Kazaa client can be downloaded free of charge and is financed by attached
Spyware (despite the "No Spyware" message displayed on their website).
Kazaa and the FastTrack protocol are the brainchild of the
Scandinavians Niklas Zennström and
Janus Friis and were introduced in March
2001 by their
Dutch company Consumer Empowerment. It appeared during the end of the first generation of P2P networks –
Napster shut down in July of that year.
The bulk of its initial userbase was made up of users of the
Morpheus program, formerly a client of
MusicCity . However, once the official Kazaa client became more widespread, its developers used their ability to automatically update it, changing the protocol in February
2002 to shut out Morpheus clients when its developers failed to pay license fees. Morpheus subsequently became a client of the
Gnutella network.
Like the creators of similar products, Kazaa's owners have been taken to court by music publishing bodies to restrict its use in the sharing of
Copyrighted material. Consumer Empowerment was taken to court in the
Netherlands in 2001 by the Dutch music publishing body,
Buma/Stemra . In November 2001, the court ordered Kazaa's owners to take steps to prevent its users from violating copyrights or else pay a heavy fine. Consumer Empowerment responded by selling the Kazaa application to a complicated mesh of offshore companies, primarily
Sharman Networks , headquartered in
Australia and incorporated in
Vanuatu .
In late March 2002, a court of appeal reversed an earlier judgment, and stated that Kazaa was not responsible for the actions of its users. However, in 2002, Sharman was sued in Los Angeles by the
RIAA and the
MPAA . That lawsuit is still pending, although a recent judgement by the Ninth Circuit Court of Appeals in a related lawsuit against a similar FastTrack client
Grokster appears to take away the basis for the US Kazaa suit. That decision was appealed to the
US Supreme Court , and a decision reached in
The Case , unanimously in MGM Studios' favor.

In September 2003, the RIAA filed suit in civil court against several private individuals who had shared large numbers of files with Kazaa; most of these suits were settled with monetary payments averaging $3,000. Sharman Networks responded with a lawsuit against the RIAA, alleging that the terms of use of the network were violated and that unauthorized client software (such as Kazaa Lite, see below) was used in the investigation to track down the individual file sharers. An effort to throw out this suit was denied in January
2004 .
In February 2004, the
Australian Record Industry Association (ARIA) announced its own legal action against Kazaa, alleging massive copyright breaches. The trial began on
November 29 2004 . On
February 6 2005 the homes of two Sharman Networks executives and the offices of Sharman Networks in Australia were raided under a court order by ARIA to gather evidence for the trial.
On
September 5 2005 , the Federal Court of Australia issued a landmark ruling that Sharman, though not itself guilty of copyright infringement, had "authorised" Kazaa users to illegally swap copyrighted songs. The court ruled six defendants - including Kazaa's owners
Sharman Networks , Sharman's Sydney-based boss
Nikki Hemming and associate
Kevin Bermeister - had knowingly allowed Kazaa users to illegally
Swap copyrighted
Songs . The company was ordered to modify the software within two months (a ruling enforceable only in Australia). Sharman and the other five parties also face paying millions of dollars in damages to the record labels that instigated the legal action.

On
December 5 2005 , the Federal Court of Australia ceased downloads of Kazaa in Australia after Sharman Networks didn't modify their software by the
December 5 deadline. Users with an Australian IP address are greeted with the message "Important Notice: The download of the Kazaa Media Desktop by users in Australia is not permitted" when visiting Kazaa website. An appeal will take place in February 2006.

In 2005, Sharman Networks opened a branch office in
Amsterdam ,
Netherlands .
Kazaa has, from early on, been accused of installing
Malware onto users' computers. Sharman, Kazaa's home company, claims that the products are not adware and do not collect personal user information. At one time, the part of the Kazaa code which was considered adware was an optional part of the Kazaa program, albeit one technically difficult to omit during installation. Since the allegations have surfaced, however, the code has been bundled into the main Kazaa software, and it is not possible to uninstall it. Also, spyware detection and removal software has frequently failed to delete the code without special actions taken by the PC user.
Malware installed by Kazaa includes the following:
- - Collects information on the PCs surfing habits and passes it on to the company which created Cydoor.
- - An add-on which causes advertising popups if the PC accesses a website which triggers the B3D code.
- - A distribution network for paid "gold" files.
- - Identifies your interests based on some of your computer usage and some of your web surfing behavior, including the URLs of Web pages viewed by you and other criteria. ''Versions of Kazaa released after 16 August 2005 do not have this.''
- - Redirects your URL typing errors to InstaFinder's web page instead of the standard MSN search page.
- - The toolbar monitors all the sites you visit with Microsoft Internet Explorer and provides links to competitors' websites.
- - A browser plugin that lets you access several of its own unofficial Top Level Domain Names , e.g., .chat and .shop. The main purpose of which is to sell domain names such as www.record.shop which is actually www.record.shop.new.net.
As a result of these additional components, CNET's Download.com site stopped the distribution of KaZaA in April 2004.

is an unauthorized modification of the Kazaa Media Desktop application which excludes adware and spyware and provides slightly extended
functionality. It became available in April 2002. It can be downloaded free of charge, and as of mid-2005 is almost as widely used as the official Kazaa client
itself. It connects to the same FastTrack network and thus allows to exchange files with all Kazaa users. It was created by third party programmers by modifying
the
Binary of the original Kazaa application. Later versions of Kazaa Lite included , a memory patcher that removed search
limit restrictions, multisource limits, and set one's "participation level" to the maximum of 1000. Sharman Networks considers Kazaa Lite to be a
Copyright
violation.
After development of Kazaa Lite stopped, and '''Kazaa Lite Tools''' appeared. Although K-Lite is related to Kazaa Lite and the name sounds
similar, they are actually different projects. K-Lite is not an update to Kazaa Lite, and was instead written as a separate loader with many fundamental changes.
Unlike Kazaa Lite, which is a modification of an old version of Kazaa, K-Lite v2.6 requires the original KMD 2.6 executable to run. K-Lite doesn't include any
code by Sharman: it requires the user to supply the original, unpatched Kazaa Media Desktop, and they execute it in an environment which removes the malware and
adds some features. The authors believe that this version might therefore be legal. They also hope that since this client uses a newer version of the actual
Kazaa program, they won't be affected by attempts to block Kazaa Lite from the network.
In November 2004, the developers of K-Lite released , which similarly requires the KMD 2.7 executable. Currently, other clean variants use an
older core (2.02) and thus, K-Lite has some features that others will never have. K-Lite includes multiple search tabs, a custom toolbar, and autostart. It also
has auto search more, a download accelerator, an optional splash screen, preview with option (to view files you are currently downloading), an IP blocker, Magnet
links support, and ad blocking, although the clients based on the 2.02 core abstract these functions to third-party programs.
on the other hand is in fact an update of the original Kazaa Lite. It's a copy of Kazaa Lite, with modifications to the third-party programs included. It has newer, more and better third-party programs included.
is a duplicate of Kazaa Lite 2.4.3. KLR, once thought to be a malicous program, is in fact not. KLR, is completely free of adware, spyware, and malware. Kazaa Lite Resurrection has updated versions of thrid-party programs. '''Klr is the only client that will link you to a remote page that has ads (aka start page) you can change this if you wish but original klr install will link you to the start page with ads.'''
In August
2003 , was introduced by Sharman Networks. This is a paid-for premium version presumably with no spyware or adware though the
attached
Adware ,
Spyware and
Malware is still included. In an attempt to cash in on the Kazaa name, another commercial version called '''Kazaa
Gold''' was produced. This was not an actual product of Sharman Networks. However in
2004 , Sharman Networks started buying the domains owned by these
companies and some like the Kazaa Gold one now redirect to the real Kazaa site.
