I was in Res last year and thanks to some creepy guy on our floor, I, like most people on my floor, stayed out of the common room. I didn't want to pay for TV in my room because I figured it'd be way too big of a distraction, so I basically went 4 months without any real TV exposure (with the odd hockey game, etc.).
Then, I had a 3 week break for Christmas when I went home. I tried to watch TV, but I just couldn't. I had never realized just how bad it actually was. While there were some shows I was still interested in, I hated having to wait to watch them. Commercials didn't bug me too much, but organizing my schedule around something so trivial had become incredibly foreign to me. I could never watch things like The Daily Show or South Park because I would routinely forget about them.
So, I just gave up on it. Interestingly enough, when we moved into the apartment back in September, 3 of the 4 of us decided that we didn't want cable. It was expensive and deemed a general waste of time/distraction.
I really wish they would setup a system where I could pay to download episodes or something. I'd really be willing to pay for the shows that I download, but I'm not going to pay a bunch of money for a few shows that I occasionally watch and will most likely miss.
