Google's YouTube video-sharing site has signed a deal to air more than 4,000 hours of free video content from the Digital Music Group.
Digital Music, which distributes films, television and music online, will receive a cut of the advertising revenue.
As part of the deal, YouTube will use filtering technology to identify videos on its site that feature Digital Music's copyrighted songs.
Meanwhile, Apple's iTunes service has begun selling films from Lions Gate. The iTunes service will eventually carry 150 titles from the independent movie studio.
Titles now available to US consumers include Saw, Basic Instinct and Dirty Dancing: Havana Nights.
