Kazaa Media Desktop (once stylized as "
KaZaA", but now usually written "
Kazaa") started as a
peer-to-peer file sharing application using the
FastTrack protocol licensed by Joltid Ltd. and operated as Kazaa by
Sharman Networks. Kazaa was subsequently under license as a legal music subscription service by Atrinsic, Inc. As of August 2012, the Kazaa website is no longer active.
