Hulu, the new joint internet video venture by News Corp and NBC Universal, has launched its beta.

The interesting question? Where’s the Facebook App?

Hulu has “partnered” with MySpace. It’s clear that while Hulu wouldn’t have a guaranteed distribution channel on Facebook, it could at least be in the field. Unless, of course, someone’s holding it back.

Is Rupert Murdoch trying to keep Hulu’s content isolated on MySpace? Or is the team nervous that the publicly available stats on Facebook would be more difficult to spin than content on a controlled channel?

Whatever is keeping Hulu controlled, there’s a reason for it. And Facebook’s success undoubtedly factors into the equation.
