The best thing to happen to TV since the remote

Tivo. Need I say more? Whoever invented tivo.... genius. (Not to mention probably ridiculously wealthy at this point.) I recently purchased and installed a tivo and I love it. You get to watch the TV shows you like when you want to, and you get to fast forward through commercials!

The other noteworthy thing I've discovered lately is Pandora Radio. Check it out if you haven't already!
