I don't follow football but tend to watch the superbowl if I'm somewhere to watch it. Last year I was at work, so we had the 16' video wall that the NOC uses for monitoring, we watched it on there. Management actually said the NOC /had/ to watch the superbowl since it was such a highly-watched event and they needed to know if there were any issues. So I worked in the NOC that night and had some of their pizza.
When I was living in Troy I didn't have cable so I only watched it if I was on campus somewhere and it was on. Now that I have cable at home (and my new HDTV), I'll watch it here.
