When I was a kid, I didn't know a lot of the shows I was watching were already considered "old". I was lucky enough to live in a backwater mid-western U.S. TV market where they filled airtime with shows like "Time for Beany", "Tom Corbett, Space Cadet", old serials, and other stuff that was typically considered too poorly produced for broadcast.
Our radio was similar, lots of old dramas from the prior three decades. I thought they were being performed as I listened on my crystal set at all hours.
I learned that every alien planet looks exactly the same: a box draped with a cloth with a plaster of paris rock on top with a "rock" wall to one side. Different planets, or different parts of the same planet were shot from different angles. Just outside the bad guy's lair had the rock wall on the right, near the hero's spacecraft had the rock wall to the left.
Also, the bad guys' ships look pretty much the same as the good guys' ships, there's usually something on the control column to mark the difference. Every ship has a side door to get in and out of normally, a trap door to jump out of in flight, a control seat with a console, and there's a small closet of some sort just big enough for someone to hide in, or hide a body in.

I love archive.org. It's almost as good as having a time machine to go listen to my crystal set or the old Zenith twelve-channel 10" TV that had been abandoned in the basement. Plus, it's cheaper and easier than mailing reel to reel or cassette tapes back and forth to other OTR fans.
