Its a style that came & went over the years. Some 50's
bug eyed Zeniths are narrow. Many early 60's were made
in the suitcase or attache style. "Top Tuning" sets were
also narrow. For color the mid 70's Sony 17" comes to mind
first. All controls on bottom & it looked real odd to us.
In the 80's it became the "cube" style. That spred like wild fire
since you can get a 25" into an area a little bigger than a typical
19-20" Enuf
