Napster

Napster was an American peer-to-peer (P2P) file sharing application primarily associated with digital audio file distribution. Founded by Shawn Fanning and Sean Parker, the platform originally launched on June 1, 1999. Audio shared on the service was typically encoded in the MP3 format. As the software became popular, the company encountered legal difficulties over copyright infringement. Napster ceased operations in 2001 after losing multiple lawsuits and filed for bankruptcy in June 2002.

The P2P model employed by Napster involved a centralized database that indexed a complete list of all songs being shared from connected clients. While effective, the service could not function without the central database, which was hosted by Napster and eventually forced to shut down. Following Napster's demise, alternative decentralized methods of P2P file-sharing emerged, including LimeWire, Gnutella, Freenet, FastTrack, and BitTorrent.

Quotes about Napster

• Napster affected rock CD sales disproportionately when it first came out in the late ’90s, because rock was what a lot of college students were listening to, and they were early MP3 adopters (and early pirates.) They figured out quickly how to download MP3s for free, so rock sales were the first to decline. It would take a while before piracy/the Internet/MP3s/downloads would cut into other genres, because it took old people a long time to figure out the Internet. [...] Everyone would suffer, but those artists and labels would feel it first and worst. After all the good times, this one-two punch at the turn of the millennium left indie — and rock music in general — reeling.
