" ‘The Flintstones’ was the first animated series to appear on nighttime TV. "
- William Hanna

The statement suggests that "The Flintstones" was a groundbreaking show as it was the first animated series to be aired on prime-time television, typically reserved for live-action programming. This indicates a significant shift in how animation was perceived and presented to the audience.

Exploring beyond its literal meaning, this quote underscores the revolutionary impact of "The Flintstones" on television broadcasting and cultural norms. Prior to this series, animation was primarily associated with children's entertainment and aired during daytime hours or late at night when fewer viewers were watching. By moving an animated show into prime-time slots, it opened up new possibilities for storytelling and expanded the audience reach for animated content. This move likely influenced future television producers and animators by showing that animation could appeal to a broader demographic, including adults. Consequently, "The Flintstones" set a precedent for the industry, proving that quality animation can captivate viewers at any time of day.

William Hanna is one half of the renowned cartoonist duo William Hanna and Joseph Barbera, who are celebrated for their extensive contributions to animated television and film over several decades. Known for creating beloved characters such as Tom and Jerry, they were instrumental in developing the concept of prime-time animation with "The Flintstones," showcasing their innovative approach to storytelling and broadcasting.
