I'm not sure how long they've been doing this...or how long they'll get away with doing it (surely someone is suing them?), but this site based in the UK has aggregated a ton of content of current and past TV shows (American and British), as well as hundreds of full-length movies, documentaries and music videos, making them all viewable onscreen...for free.
Now, I don't watch a lot of TV that doesn't involve a game played with a ball of some sort, so I probably won't spend a lot of time here. But it's a heck of a resource, if only for trivia question research. Check out the movie section too.
