EMI started the anti-DRM movement by being the first major record label to sell their music without DRMs. Fortunately, Universal Studios caught on quick, and now offers the majority of their library sans DRMs to select retailers. And thanks to a recent promotion of the Amazon DRM-free music selling service, and a new partnership of said music service with Pepsi, more record labels are planning to sell DRM-free music. Warner Music Group, who owns material from famous artists such as Black Sabbath, is planning to put their music on Amazon. Sony BMG is also planning to place their material on Amazon. The main reason behind this sudden adoption of DRM-free material is the recent success behind DRM-free music. A symbol of this success is Universal making 85% of their music available as an unprotected MP3 file. Universal is all but confirmed as staying in the DRM-free MP3 market, pending final results of the market trial due in mid-January.
