Warner Bros. Home Entertainment Group on Tuesday became the latest division of a major Hollywood studio to offer television shows, including the hit sitcom Friends, for sale on Apple Computer Inc's iTunes Web site.

Warner Bros put up a total of 113 episodes of Friends, sci-fi series Babylon 5, the animated classics The Jetsons and The Flintstones, as well as skits from MADtv and an unaired pilot called Aquaman by the writers of Smallville.

Downloads cost $1.99 per episode, and can be viewed on a computer or video iPod.

Warner Bros, owned by Time Warner Inc, said the move to iTunes was aimed at making its vast library of TV shows available across a wider array of viewing platforms.

The studio is the latest to join the rush by content providers to generate revenue from their libraries as growth in DVD sales and television viewership stall.

Apple's iTunes store now offers a total of more than 150 TV shows available for purchase from the Fox, ABC, NBC, CBS and MTV networks.
