If I may ask, what makes you assume they do? I haven't followed any shows since BSG ended, and my wife watches 2-4 hours a week of stuff she probably wouldn't miss all that much. Our daughter watches an hour of kid stuff (Dora, etc.) every day (1/2 hour during breakfast, another 1/2 hour while I cook dinner), but generally prefers to spend her time playing with my wife and I. If I were to sell the TV on craigslist tomorrow there would probably be some whining for a week or three, but eventually we'd settle down into a new routine and probably never miss it.

When I "consume content," it generally comes sandwiched between a couple of paper or cardboard covers.
