Eventually, the official Kazaa client became more widespread. Initially, some users of the Kazaa network were users of the Morpheus client program, formerly made available by MusicCity. Skype itself was based on Kazaa's P2P backend, which allowed users to make a call by directly connecting them with each other. Kazaa was introduced by the Dutch company Consumer Empowerment in March 2001, near the end of the first generation of P2P networks typified by the shutdown of Napster in July 2001. Kazaa and FastTrack were originally created and developed by Estonian programmers from BlueMoon Interactive including Jaan Tallinn and sold to Swedish entrepreneur Niklas Zennström and Danish programmer Janus Friis (who were later to create Skype and later still Joost and Rdio).

During the years of Kazaa's operation, Sharman Networks and its business partners and associates were the target of copyright-related lawsuits, related to the content distributed via Kazaa Media Desktop on the FastTrack protocol.īy August 2012, the Kazaa website was no longer active. The Kazaa Media Desktop client could be downloaded free of charge however, it was bundled with adware and for a period there were 'No spyware' warnings found on Kazaa's website. Kazaa Media Desktop was commonly used to exchange MP3 music files and other file types, such as videos, applications, and documents over the Internet. According to one of its creators, Jaan Tallinn, Kazaa is pronounced 'ka-ZAH' ( / k ə ˈ z ɑː/).

Kazaa was subsequently under license as a legal music subscription service by Atrinsic, Inc., which lasted until August 2012. and operated as Kazaa by Sharman Networks. Kazaa Media Desktop (once stylized as ' KaZaA', but later usually written ' Kazaa') was a peer-to-peer file sharing application using the FastTrack protocol licensed by Joltid Ltd.
