From Woman's Day Home Decorating Ideas, 1974: "Don't hide your TV set, don't just put it anywhere. Incorporate it as part of your overall room decor. As much a part of the American scene as hot dogs, the almighty television set can be found these days in practically every room in the house. However, it's usually placed there as an after-thought and never really "fits".
This last room is my favorite!
"In the family room, three denim-paneled TV sets provide a color scheme and access to three channels at once... for the real TV fanatic." -Woman's Day, 1974
