I had a few years in the mid/late ninetys without a TV and that completely broke the spell of the telly on me. It was a bit annoying to have people blether on constantly about what they had watched the night before. Corry this, Eastenders that, did you see? at work.
These days the telly is on as a bit of background noise in the evening. I've seen a few progs recently that I've enjoyed. But as cunobelin has said anything with the word celebrity gets turned off as do any X factor/jungle/"Britain's talentless" type programmes. My wife has recently discovered "Say yes to the dress", now that is seriously grim TV!!!
