We got our first TV in 1948. I lived in the NY metropolitan area, (north Joisey) and we could see the TV antennae on the Empire State bldg. Sid Caesar, Amos and Andy and of course Captain Midnight, Captain Video and Tom Corbett Space Cadets. Those made me the space geek that I am today.
Then there was Superman and Howdy Doody! Wowser
Tom Corbett Space Cadets. I never knew there was a TV show on that. I just read from that character/story line I don’t know how many cheap novels from the library. It was a major competitor of Tom Swift stories.
It wasn't "the" first broadcast. That would have to be credited to J.L. Baird.
If anyone wants to get really nostalgic, how about the old radio shows. I remember gathering around the radio, and listening to 'The Shadow Knows', The Life of Riley', and Fibber McGee's Closet'.
