Digital rights management (DRM) is a class of access control technologies that are used by hardware manufacturers, publishers, copyright holders and individuals with the intent to limit the use of digital content and devices after sale. DRM is any technology that inhibits uses of digital content that are not desired or intended by the content provider. DRM also includes specific instances of digital works or devices. Companies such as Amazon, AT&T, AOL, Apple Inc., BBC, Microsoft, Electronic Arts and Sony use digital rights management. In 1998 the Digital Millennium Copyright Act (DMCA) was passed in the United States to impose criminal penalties on those who make available technologies whose primary purpose and function is to circumvent content protection technologies. The use of digital rights management is controversial.
