Wal-Mart said the download service includes more than 3,000 titles from movie studios like 20th Century Fox, Disney, Lions Gate, MGM, MTV Networks, Paramount Pictures, SonyPictures Entertainment, Universal Studios Home Entertainment and Warner Bros. and television networks including Comedy Central, Fox, and Nickelodeon.
The downloads are priced from $1.96 for episodes of television shows to up to $19.88 for new movies.
Retailers have been exploring ways to capitalize on the emerging market for downloading movies and TV shows from the Web. Last year, Wal-Mart announced a test of a service offering consumers who bought a physical DVD the option to download the film for an additional fee.
Wal-Mart said in the service being introduced on Tuesday, movie releases will be available for video download the same day the DVD is released.
The retailer said the service is powered by technology from Hewlett-Packard.
