"Who wants a tape-cartridge recorder?"
Not enough people, obviously, since I'll bet you've never seen one of these things. This RCA tape-cartridge recorder is a 1959 model, and it's kind of like a cassette deck, only bigger. With better fidelity, too, because it's basically a reel-to-reel machine with the reels in a great big cassette . . . er, cartridge.
It never stood a chance when little cassettes came along in the mid-1960s.
The world is filled with Philistines! Any idiot knows that
HEY! You can't argue with "four and one-half years of research."
Well, you can, but that just makes you an audiophobe. Philistine.
