Were there any primetime cartoons between "The Flinstones" and "The Simpsons"??

If there were -- they obviously werent successful.

why yes, there's

The Bullwinkle Show
Top Cat
The Alvin Show
The Jetsons
Johnny Quest
Calvin & The Cournel
The Bugs Bunny Show

I believe "Wait Till Your Father Gets Home" was a prime time toon too.
