Answer: The Flintstones
“The Flintstones” took us back to the Stone Age for a whopping six seasons starting in 1960. This show was so popular back in the day that it became the first animated series to snag a prime time television spot. That’s a pretty big deal because most cartoons at the time were strictly reserved for Saturday mornings. To this day, people love the clever way the show weaves modern issues with funny references to a romanticized Stone Age. “The Flintstones” were so popular that they were the most financially successful cartoon until “The Simpsons” came on the scene in the 90s.
