PressPlay (stylised pressplay) was the name of an online music store that operated from December 2001 until March 2003. It was created as a joint venture between Universal Music Group and Sony Music Entertainment in response to the popularity of Napster. Universal and Sony created PressPlay rather than joining RealNetworks' online service MusicNet, which had signed BMG, EMI and AOL Time Warner. It was originally announced under the name Duet in May 2001 and launched as PressPlay in December 2001.
