Protecting digital rights

The Internet has made it possible to distribute and exchange various forms of digital media (e.g., music, video, etc.) cheaply. End-users now have an effective, low cost means to distribute, search and obtain digital content. Some end-users now even expect the content to be free, causing the intellectual property to holders find new approaches to obtain revenues from the use of the content. As new technology is being developed to make it easier to obtain digital content, a fast growing industry is forming to control the use of digital content.
