Fox announced today that it has signed a deal with Apple to provide season premieres of seven of its shows for free over iTunes. The contract comes amid much news from networks regarding online television options. Here's the rundown:

• Fox will give away downloads of seven of its shows -- including "Prison Break," "Bones," "American Dad" and "K-Ville" -- on Apple's store. The episodes usually sell for $1.99, and they contain no advertisements; iTunes shows can be played on PCs, Macs and, using an iPod, iPhone or Apple TV, on your television. Only the season premiere of the Fox shows will be free, and only for the next two weeks. The network's rationale here is straightforward: New shows -- and even returning old shows -- need to build up an audience quickly in the new season, and the networks hope free downloads will get a lot of people hooked. Something like the logic of the cigarette business, you might say.
• ABC says it will put some if its shows on AOL's video-streaming site. This is meant mainly for watching at your computer. (Yes, A.V. club members, I know it's possible to connect a computer to a TV.) The move is just a slight addition to ABC's previous strategy of streaming its shows on its own Web site -- the company will keep doing that, and AOL is just another place where people can find "Grey's Anatomy," "Cavemen" and other offerings. The streaming shows will contain advertisements. ABC is owned by Disney, of which Apple CEO Steve Jobs is the largest shareholder, so naturally, ABC's shows are also available on iTunes.
• NBC, oh NBC, folly be thy name. I mean to say, Did you play with a lot of lead-painted Barbies when you were small, NBC? Because seriously, this is not a smart move: After famously walking away from iTunes last month -- NBC wanted to raise the price of downloads, Apple wanted to lower it -- the network is offering a new plan to put its shows into nerds' hands. The company says that in October it will launch NBC Direct, a system that will let you download network shows for "free."
