50. The Jetsons

Launched by the legendary Hanna-Barbera animation studio as the the Space Age equivalent of The Flintstones, The Jetsons was a lighthearted comical take on the future that originally ran for just one season and 24 episodes between September 1962, and May 1963.

Far from being cancelled because of its quality, The Jetsons premiered when less than 3 percent of households had a color television, so most viewers were unable to appreciate the beautiful, bright visuals of the futuristic world.

The Jetsons actually did a pretty good job of predicting the future, too. Sure, aliens aren’t our neighbors and we’re not zooming around in flying cars (yet), but we do communicate on video chat and robots are taking humans' jobs every day.

As the years went by, The Jetsons became more and more of a cult commodity, so much so that it eventually returned for two more seasons in 1985.
