I would say my TV habits have changed over the last few years. Being so busy I rarely wind up in front of the tv when a show is actually on so DVR has allowed me to follow certain shows and sports I'd long since given up trying to follow (On Demand serves the same purpose I suppose). HD tv and plasma screen...whatever TVs play a roll as well, I don't think I watch anything outside of the HD channels anymore which is a major change because I'm now limited to maybe 70-80 channels, less channels better picture I suppose
Anyway other then that I don't really have any habits. TV is really just something I use to unwind at the end of the day and keep the old stress levels in check. But during those two or three hours I plop my ass down on my couch, just kind of veg out and try to think as little as possible.
