WATCH ONLINE: ABC hops on Hulu

Hulu is heading toward behemoth status. The NBC/Fox-launched TV streaming site today adds the ABC corporate family to its hosted offerings. That means episodes of shows from ABC (starting with Grey's Anatomy), ABC Family, Disney Channel, SOAPnet and more, all in the familiar clean Hulu interface.

Other ABC-owned shows are being linked from their own sites for now, like The Secret Life of an American Teenager from ABC Family. Expect moves onto Hulu in coming weeks.

That leaves CBS the lone Hulu holdout among major networks, alongside its CW sibling (though Hulu does link to their CBS site streams). CBS has a pretty clean and fast interface of its own, and has been a network leader in original production for its web site (creating series like the soaps-based reality competition InTurn).

Launched in March 2008 by NBC and Fox, Hulu heightened its profile in past months with science-fictiony ads featuring Alec Baldwin and Seth MacFarlane as alien invaders taking control of Earth through online TV. The service claims more than 40,000 videos for viewing (some are clip-length), from more than 130 content partners, watched by more than 24 million users a month.
