All right, so that's a bit dated, but the point remains: Nothing important is going to happen with people sitting on their asses in front of TVs all the damn time.
Even when I used to get any channels on my TV, I still rarely watched any shows when they actually aired because 1) commercials suck and 2) I refuse to let my schedule be dictated by some random producer. These days, I don't watch anything except DVDs for basically the same reasons, with the additional motivations of more reading, loving, cooking & exercise time for myself.
Basically, without letting TV serve as the focus for my evening, I feel I have much more connection with myself and the people around me. The Magical Power of Focus post from Zen Habits puts it this way:
If we focus on being tired and wanting to veg out in front of the TV, we will get a lot of television watching done. If, however, we focus on being healthy and fit, we will become healthy and fit through exercise and good eating.I don't think people use the TV as a substitute for really living their lives on purpose (and I know plenty who don't do it at all and still enjoy a good veg), but the question I'd like to ask you is this: What would you do if you had to spend one week TV free?
