Apple has added more video content to the iTunes Music Store, which probably needs to be renamed as the video becomes a bigger piece of what is sold. Current shows added include The Office and Battlestar Galatica, as well as a bunch of older shows, ranging from Knight Rider to Alfred Hitchcock Presents. The deal is with NBC Studios.
In the few months that video has been available for sale from Apple, the company has sold more than 3 million episodes at about $2/piece.
