In his recent New York Times article, "Sneaking Into the Movies," Michael Cieply describes how large media companies are using both carrots and sticks to ensure compliance with copyright laws.

The carrots are not well-known, but primarily involve creating "events" around the music and movies, such as using concerts-not records-as a primary revenue stream for performers and creating one-of-a-kind events around movies, which viewing the video can't repeat (like the opening events associated with Disney's documentary, Earth.)
