Yes, kind of.
In our first home we had one in the bedroom and one in the living room, like you do now. We don’t have a tv in the bedroom now.
In subsequent homes we have turned the dining room into a second living room, or play room as we call it, because it has the PlayStation x box etc in there, and it gets much more use than a dining room for us, as we have a dining kitchen and although we socialise a lot, I don’t do formal dinner parties and we all eat in the kitchen.
We tend to watch the tv together, I’m not a big tv watcher, so don’t mind if my husband is watching sport, but if I really want to watch something and He wants to watch something else, he will go into the other living room to watch it. It’s rare though.
The tv in that room is mainly used for gaming , as both my husband and daughter like to game, I seldom ever use the room and can’t recall ever watching a tv program in there to be honest.
So yes, basically we have a separate room with a tv etc in it that we can use if we wish to watch separate programs.
