NBC and Fox have launched Hulu, which has free streaming video of their TV shows and many movies, with limited commercial interruption. It’s nice actually to have a permalink to a TV show, like if you want to reference a joke on The Simpsons, you could link right to it. I’d like to see Google build a good index of what’s available, though, so that I don’t have to remember what network a show was on to find its videos.
