DRM is Digital Rights Management (DRM); in basic terms, it's the ability to brand your digital media, either music or video, with attributes that ensure copy protection in the way in which your media is played back.

Downloading encoded files has gained acceptance among Internet-savvy users because it provides immediate access to desired content and does not require a trip to a store or reliance on physical media, such as a CD or DVD. However, digital media content that is available for sale on the Internet is still limited, as content owners, artists, and publishers are concerned about protecting their copyrighted works from illegal use.
