Barney Rubble is the secondary main character of The Flintstones, an animated, prime-time American television sitcom that was broadcast from 1960 to 1966 on ABC. The show, produced by Hanna-Barbera, fancifully depicted the lives of a working-class Stone Age man, 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 Magazine ranked The Flintstones as the second greatest TV cartoon of all time (after The Simpsons). Barney Rubble and other characters from The Flintstones have been mascots of Fruity Pebbles and Cocoa Pebbles breakfast cereal since 1969.
