Online video site Hulu launched last year as a partnership between NBC Universal and Fox. Unlike other online video sites, Hulu isn't about video sharing - it's about internet television.
Now, Disney is getting in on the deal. Disney owns ABC, so this will have three of the top four broadcast networks participating in Hulu. CBS is the outstanding one, and while you can search for shows like CSI, ultimately you'll be taken to the limited CBS site.
Last month, YouTube announced a deal with CBS, but so far the offerings are pretty paltry.
