I moved to a new apartment a few years ago. I initially planned to set up cable at the new place, but didn't have time to think about it for the first few weeks after the move. By the time it occurred to me to call Comcast, I realized how little I missed my television, and just decided to skip it.
I continue to not miss it at all. If I want to watch a football game, I just grab some dinner or lunch at a bar and watch the game. If I really want to watch some show, I watch on my computer (this doesn't come up too often). Otherwise, there's really no shortage of other stuff to do.
When I visit my family and am reminded of how TV obsessed the average person is, I am pretty glad that I didn't go down that road. Everyone comes home at the end of the day, and the kids plop down in front of one TV, the parents plop down in front of another TV, and grandpa sits in front of a third TV. There they remain until bedtime with a short break for dinner. To each his own, but that just seems miserable to me.
