My wife and I have had a policy since we got married. It wasn't so much intentional as an opportunity we snagged. We got a VCR for a wedding present and it had four programmable slots on it. We decided that we weren't going to adjust our schedule for TV in any way. If we could record it, and it moved as to sit down and watch at some point, we'd record it.
Every fall, I look at the shows that are coming out and pick a few that look interesting (I know my wife's tastes). We often, but not always, watch the premieres live and then decide what is worth filling up one of the four slots. When all our shows' seasons end, we clear the VCR and don't turn on the TV until the next fall. I dislike midseason replacements and hate the summer seasons -- they are just too hard to figure out, so I don't bother.
Sometimes shows get dumped (Andromeda looked promising), sometimes they get added on recommendation of others (Smallville), and sometimes we cheat (when Buffy and Angel were back-to-back, it gave us an extra 'slot'), sometimes we don't use all the slots, and sometimes we miss one (Kingdom Hospital). Overall, though, the system has worked pretty good for nine years. It also helps that we don't buy the cable channels -- SciFi, History, and Discovery would eat my soul.
We haven't watched broadcast TV since about April or May. Don't miss it in the least.
Honestly, I still don't have time to do everything that I want to do. I look at some of my friends who watch 2+ hours of TV on an average night and marvel.
