Hulu is not only a destination where I went to watch television. It is also a hub from which NBC Universal and News Corporation distribute content either by allowing users to
embedvideo or by partnering with other web sites. Due to the former, I can
embedvideo in my blog for free. Because of the latter, there are a number of web sites on which I can watch the same content.
OPENHulu uses the
embedcode from Hulu just like I could on my blog.
Veoh works just like OPENHulu; that is, it uses the
embedcode just like I could on my blog.
Fancast aggregates content from CBS, USA Network, Sci-Fi, and from Hulu. (So is Hulu a competitor or a wholesaler?)
ABC has a great site for their own shows. You have to download a plug-in but it was painless and the player has great controls.
TV4U is a strange-looking little site replete with episodes of rare classic television shows from the fifties and sixties, commercials and movies. I think it is all public domain and very well done.
Public Domain Movies is another site for the titular films. Well-organized and official-looking.
TV @ AOL Video is similar to Hulu and, in fact, carries their content. The difference between them all is getting murky though - maybe this site carries Warner stuff in addition?
Joost is one I just discovered and haven't delved too deeply into BUT it has Divorce His/Divorce Hers, the ABC Movie of the Week starring Elizabeth Taylor and Richard Burton. Lookin' good.
Metacafe is similar to YouTube.
