An online music store is an online business which sells auio files, usually music, on a per-song and/or subscription basis. The Internet's first free high fidelity online music archive of downloadable songs was the Internet Underground Music Archive. IUMA was started by Rob Lord, Jeff Patterson and Jon Luini from the University of California, Santa Cruz in 1993 The realization of the market for these services grew widespread around the time of Napster, a music and file sharing service created by Shawn Fanning that made a major impact on the Internet scene during the year 2000. Some services have tethered downloads, meaning that playing songs requires an active membership.
