We have a TV but we don't get broadcast television, only on-demand. You don't have to invite the worst people in - for example we've sat down and watched the RI Christmas lectures (http://www.rigb.org/christmas-lectures) together.

We also use the TV for gaming/DVDs.

Initially we went cold turkey on the TV but then we used one for DVDs only and eventually slipped back to watching shows (primarily via BBC iPlayer). Partly because we hadn't accounted for the cost of the hobbies we dreamt of filling our time with; instead we continue to live vicariously through the on-screen experiences of others.
