TV Squad reports that FOX will produce some original, web-only episodes of Family Guy. According to the post:

At some conference in New York, the head of interactive media at FOX said in a speech that they are planning to create some original episodes of Family Guy for the web. He's not sure of distribution plans yet, but now that FOX owns MySpace and IGN, those are likely places to place video content. It could also appear on FOX.com. Just like the other networks, FOX will charge (about $2) for each downloaded episode.

Commenters on the thread speculated that this might be tied into Apple's announcements of a new home media Mac in January – scuttlebutt has it that they'll be launching a more intense online video initiative as well.
