DrakkenZero, TV fans in their 40s... what cartoons do you remember from the 1960s and 70s were still being rerun well into the 80s?
I feel like it didn't last into the 1990s because of the glut of new animation that came from the 80s gave them a lot more cartoons to re-run, but there was definitely a time in the early-to-mid-80s where things like Super Friends, Scooby Doo, Flinstones, Hanna Barbera were being used to fill out sub-prime schedule slots.
