TIL the “20Q” (20 questions) handheld game, a toy released in 2003 actually used a basic implementation of an AI neural network. It used training data gathered from users of a web-browser based implementation of the game which launched in 1994.
I remember I had one of these when I was a kid and it was shockingly accurate. Pretty cool to see that it actually used a form of a nureal network to accomplish its guesses.
