The Pebbles and Bamm-Bamm Show is an American animated television series produced by Hanna-Barbera Productions that originally aired for one season on CBS Saturday morning from September 11, 1971, to January 1, 1972. With an ensemble voice cast of Sally Struthers, Jay North, Mitzi McCall, Gay Hartwig, Carl Esser and Lennie Weinrib, the show follows teenage Pebbles Flintstone and Bamm-Bamm Rubble as they encounter problems growing up in the fictional town of Bedrock. The Pebbles and Bamm-Bamm Show is the first spin-off series of The Flintstones. For the 1972–73 season, the show was revamped as The Flintstone Comedy Hour, with more time given to the original Flintstones cast alongside both reruns and newly produced segments of Pebbles and Bamm-Bamm.
