Kazaa soon became the most popular file-sharing service on the Internet, with millions of users simultaneously sharing content.But with unlimited file sharing comes the big question: Should users be granted unrestricted -- and free -- access to copyrighted movies, music and games?As of August 2012, the Kazaa website is no longer active.According to one of its creators, Jaan Tallinn, Kazaa is pronounced ka-ZAH.Fast Track is a so-called "second generation" P2P protocol.The system divides Kazaa users into two groups: supernodes and ordinary nodes.However, some services, like Lime Wire, Scour, Grokster, Madster, and e Donkey2000, were brought down or changed due to copyright issues.Kazaa Media Desktop (once stylized as "Ka Za A", but now usually written "Kazaa") started as a peer-to-peer file sharing application using the Fast Track protocol licensed by Joltid Ltd. Kazaa was subsequently under license as a legal music subscription service by Atrinsic, Inc.
Later companies and projects successfully followed its P2P file sharing example such as Gnutella, Freenet, Kazaa, Bear Share, and many others.
But unlike Napster, which distributed content via a centralized server, Kazaa uses a decentralized system.
Kazaa users contact one another directly online to share content.
Just a few years later, a more wide-sweeping file-sharing network, Kazaa (or Ka Za A) emerged.
Kazaa enables its users to share not only music, but also movies, television shows and other types of digital information.
