The Flintstones is an animated, prime-time American television sitcom that was broadcast from September 30, 1960, to April 1, 1966, on ABC. The show was produced by Hanna-Barbera. The Flintstones was about a working-class Stone Age man's life with his family and his next-door neighbor and best friend. The show's continuing popularity rested heavily on its juxtaposition of modern everyday concerns in the Stone Age setting. The Flintstones was the most financially successful network animated franchise for three decades, until The Simpsons debuted. In 2013, TV Guide ranked The Flintstones the second Greatest TV Cartoon of All Time.
