The Jetsons is seen as a classic show these days that lasted 75 episodes. However, it actually got canceled after just one season on ABC in the early 1960's. It lived, mostly forgotten, until the early 1980's when it was syndicated to local stations. It quickly became a popular show that attracted attention from Hanna Barbera, who put the show back into production twenty years after the show originally left the air, an amazing feat.
