The Top Rated Online TV and Movies Site (Free n' Legal)

hulu.com
Free online t.v. has been around for sometime now, but for those of you who don't know which is the best site, or just haven't checked it out before, take a look at this site. It's completely legal because it's ad supported, which means you have to see a 7 second ad spot before the show, but everything's high quality and there's a ton of shows to choose from that come from dozens of networks.
PLUS you can watch movies on there as well. The selection is a bit random (ghostbusters and the girl next door? Really now?) but it's free...and they're always putting new ones up.
