As I watched "I Dream of Jeannie" in recent years, I realized anyone with a real interest in space travel might have watched that show. Jeannie's magic and the trouble it caused were a gimmick, but they took the space travel really seriously. They did get some laughs out of that too, but it appeared they did that right.
I disagree with anyone thinking "The Jetsons" was educational. "Jeannie" might have had a better chance since the technology appeared real.
And people thinking "The Flintstones" was educational? No one was there. It was all made up.
