Why do you guys actually remember the exact size of those old TVs? I struggle to remember the size of my current TV...
If you had one of those consoles, you'd remember it!![]()
That, plus the fact there were only a handful of screen sizes generally available then. 12, 19 and 25 inch were the most common.
Anybody remember any other sizes?

I didn't start watching it 'til 1971 when introduced to it (via the Blish books) by a friend in junior high. From then on, 5 PM was Trek time in my house.
