A new show from NBC titled "Conviction" will soon make its first airing on TV after the Winter Olympics. However, right now you can get the Pilot (Episode 1), a music video from the show, and a behind the scenes look. "Conviction" is from the creator of "Law & Order" and details a "provocative" look into New York's young assistant district attorneys.
NBC is trying to make this show a success (well duh) and is trying to use iTunes to do it. Sounds like a good idea because hey, if it's free and looks decent then a TON of people will download it.
