Hulu is an online video on demand service offering streaming video of TV shows and movies, primarily from NBC and FOX and their cable networks. Hulu has online social networking features, allowing users to clip videos, or parts of videos, from the site for posting in outside online communities. (Hulu has called this aspect video sharing, though users cannot upload content.)
Hulu video is higher quality than YouTube and other streaming video on the web, but lower than traditional television. For users, the service is free and ad-supported, with optional registration. Video downloading like Apple iTunes, for offline viewing, is not yet supported. Hulu also provides web syndication services for companies.
