I grew up with only one tv in the living room. Then I went away to college and the tv was in this separate room, so I got out of the habit of watching it. Then I moved in with my then boyfriend and he was a tv watcher, so we had one tv in the living room.
Then I got married and we had one tv in the living room. That got stolen (along with everything else of value when our house got broken into when we were on vacation) and I didn't replace it for about three years. In fact, I didn't replace it at all - my neighbor, whose father was a tv repairman knocked on my door with a used tv and asked me if I wanted it - she later told me she did it because she was tired of hearing the music blasting from our house and thought if she gave me a tv, I'd play less music.
It didn't really work out that I played less music, although I did turn the volume down. We were good friends and I hadn't realized I was playing it that loud and didn't want to continue bothering her.
So we had one tv and one computer when my kids were little. They were both in the family room. One of my students said to the rest of the class after visiting my house (he was the same age as and friends with my son) - Mrs. H. has a nice house, but I think she be POOR - they only have one tv and one computer and they're in the SAME ROOM!
I told them that was by design. I wanted to know what my kids were watching on tv and doing on the computer.
Then we moved to England where you have to pay a tv licence fee -YES - in addition to paying for cable and all that you have to pay like over £100.00 a year to WATCH TV?! That's bull - so we didn't have a tv for about five years until my kids revolted and my son bought a tv and paid the licence fee so he could watch American sports (basketball - baseball).
So now we have one tv in the living room and one computer in the office and two laptops.
I would never have a tv in my bedroom. I read in my bedroom and I can't do that with background noise.
In the kitchen I have a stereo - I listen to music while I cook.
