>Multi use rooms require TVs

That seems an overstatement. I now have one in my entire house (don't have kids).

There's a fairly large TV panel on one wall in basically a sitting room. Otherwise I just use a computer. A relative basically has TVs in every room. I guess it maybe made sense when he was rebuilding anyway but it still seems excessive to me who might sit down to watch a movie or show but doesn't have live TV.

But, then, I don't have AC either in Massachusetts.
