Red Planet Mars

I enjoyed the film, like a little snip of history, as you could "feel" the mood of the times just watching it.

What I was wondering, when you see Peter Graves watching television at home he is clearly looking at a wide (really wide) screen set seemingly embedded in a wall that is made of stone floor to ceiling.

Additionally, he has knobs on a table along side his chair to turn on and off the set.

For all intent and purpose (with the exception of no remote control) the room is set up rather like a home-theater only in 1952. Were there wide screen television able to be set into a wall with knobs on tables back then? I noticed too that the screen was surrounded by wood trim, rather like the way you see a wall mounted AC unit! Interesting.
