Content or Medium?

I watched TV for 4 hours on Tuesday! 4 whole hours of my life! I turned on the TV to watch the Republican Presidential Primary in Michigan, and I was kind of sucked in. Not only was it incredibly close as the votes came in, but there were plenty of speeches and panels to watch. So... here's where I come to the question. When we talked about books, we talked about how the content is more important than the medium (i.e. we shouldn't be okay with inappropriate books just because they are books). For me, I felt that the content of the Primary was valuable; I was getting involved in the elections (personally I feel like that is part of my civic duty) and learning about some of the most important issues. So is the fact that I was watching TV for that long bad? Would it have been different if I had been reading about the elections? Or is this just a question of excesses?
