My parents bought their first color TV in 1975 at Ollie Fretter's in Detroit. They tell me the first thing we ever watched was the Charlie Brown Christmas special. They told me that every Christmas, and probably will again this year, lol.
The set looked a lot like this one:
...but was a bit more expensive.
I sure wish I had that set today.
It never really stopped working, but got replaced in '84 and demoted to basement use. They gave it to my uncle years later to take to his hunting cabin. Those guys shot it when they tired of the shifting colors (likely from dirty module connections).
