Napster is a name given to two music-focused online services. It was originally founded as a pioneering peer-to-peer file sharing Internet service that emphasized sharing audio files, typically music, encoded in MP3 format. The original company ran into legal difficulties over copyright infringement, ceased operations and was eventually acquired by Roxio. In its second incarnation Napster became an online music store until it merged with Rhapsody on 1 December 2011.

Later companies and projects successfully followed its P2P filesharing example such as Gnutella, Freenet and many others. Some services, like Grokster, Madster and the original eDonkey network, were brought down or changed due to similar circumstances.

Napster was co-founded by Shawn Fanning, John Fanning, and Sean Parker. Initially, Napster was envisioned as an independent peer-to-peer file sharing service. The service, named after^[which?] Fanning's hairstyle-based nickname, operated between June 1999 and July 2001. Its technology allowed people to easily share their MP3 files with other participants. Its ease of use led to massive copyright violations of music and film media, as well as other intellectual property.^{[citation needed]} Although the original service was shut down by court order, the Napster brand survived after the company's assets were liquidated and purchased by other companies through bankruptcy proceedings.
