"Rosey The Robot," which premiered on September 23, 1962, was the first episode of the series.
The Jetsons aired on prime time after 16 months in development. It was set in 2062, 100 years after the first episode was broadcast.
Supposedly, the series had no chance at survival, because it was scheduled opposite "Walt Disney's Wonderful World of Color" and "Dennis the Menace," which had both built up an audience in previous seasons.
However, ABC continued to show the original 24 episodes of The Jetsons for 15 years!
