4. Hulu.com
When cable eventually dies, websites like Hulu will be held responsible. Unlike YouTube and other amateur-video-upload sites, Hulu is a hub for network TV shows and movies: Hulu offers shows from nbc, Fox, pbs and other channels, including free full episodes of SNL, The Daily Show, The Office and other hits the TiVo-less masses often miss, plus films like Ghostbusters, The Fifth Element and Lost in Translation. Created as a network-approved alternative to YouTube's grab bag, Hulu was at first roundly mocked as a ham-fisted corporate knockoff of the grass-roots glory that is YouTube. (It was also mocked for its weird name.) Instead it proved that suits can play in the Internet video space too and that studio content can coexist online with the user-generated kind. In doing so, it delivered the final blow that untethered TV from that box in your living room.
