I watch zero TV. No shows, series, sit-coms or documentaries. We have a local channel, 60, that airs Yankees & Mets games (our autistic son l-o-v-e-s the Mets & watches most of their games). When I have that on, it's on mute (unless our son is watching - but he also has an app for his HD laptop & watches on that). However, with the way the Mets always seem to grab defeat from the jaws of victory (poor clubhouse attitude, no doubt), that is becoming less frequent in the last few years.
During the day - if I'm working from home - it's the Music channel (either classic Jazz or Classical).
We don't have an HD TV, & the last time I watched with any regularity, M*A*S*H was on regular programming (not in syndication yet) - I was in college then ('77-81) & we had a TV in my fraternity house living room that I watched after getting back from studying @ the campus library.
I will put a sports channel on mute for 10 minutes in the AM as I stretch before running - simply for the sports images - other than that, I have no use for television.
