Sometime after the local TV station (50-60 miles away) came on the air, my dad bought a used TV. It was a Zenith with a round picture tube like the one below. Don't remember what happened to it, probably got killed by lightning.
It's amazing what you can find on the intratubes. It only took me a little while (10 minutes or so) to find a picture of this old TV. A lot depends on what you type into Google. Started off with Zenith round and Google suggested "Zenith roundie TV", after looking at the results for that awhile, came across Zenith porthole TVs which I put in the search and after that I found this picture. It's a 1950 model Zenith Porthole TV. This looks very similar to the one I remember us having when I was a kid.
Quite the contrast between this TV and the present one.
