The Debate Over PlaysForSure DRM
For an overview of PlaysForSure and DRM, see
Digital Rights Management (DRM).
Microsoft produces software and hardware for a variety of markets. It has produced and marketed a DRM scheme called "PlaysForSure" to many online music vendors and hardware vendors.
"PlaysForSure" is integrated with Microsoft products such as Windows Media Player and their operating systems.
Given that Microsoft has produced and marketed "PlaysForSure", the vendors which use it were surprised that Microsoft did not choose it for its Zune brand of devices and services, but rather appears to have created a new DRM scheme for the new brand.
