Vacuum tubes: Radio tubes, TV tubes, Audio tubes


Are tubes used in radio or TV different from audio tubes used in power amps and preamps?
If they are different (i.e., if tubes used in radios and TVs are different from tubes used in amp/preamps) what are the use of radio and TV tubes?
I don't see any people caring about tube radios and tube TVs as they care about tube amps, but I see a bunch of ads in eBay for selling radio/TV tubes, and just wonder.

I’ll take all the tubes from the early 40s and early 50s. You guys can fight over the rest of them.
