If the TV is on, I'll watch it. It doesn't seem to matter what is one, I get sucked in. We also do the netflix thing, and do not have cable channels, and the TV is in a back room.
I sometimes grab the remote when visiting a friend's house to turn their tv off because I cannot carry on a conversation if the tv is on. When we go out to eat my wife will scan the room before sitting at our table to be sure I am not facing a tv.
