AI could revamp the once-doomed Smell-O-Vision
When movies made the leap from silent to sound, production companies had their eyes on the next sensory frontier in entertainment. So in 1939, they attempted to bring smell into the cinematic experience. The Smell-O-Vision, a system that piped prepackaged scents from under movie theater seats, made its debut at the 1939 World's Fair in New York City. It didn't go as planned. Audiences complained that the scents were out-of-sync with the movie, overpowering, or simply unpleasant.
