Although scorned by critics, "The Beverly Hillbillies" attracted as many as 60 million viewers between 1962 and 1971 and was several times the highest-rated series on television. The show also spawned similar Paul Henning-produced rural sitcoms such as "Green Acres" and "Petticoat Junction", which were eventually linked in crossover episode arcs. "The Beverly Hillbillies" was still earning good ratings when it was cancelled by CBS (because programmers began shunning shows that attracted a rural audience). One episode, "The Giant Jack Rabbit", was the highest-rated half-hour on television to that time and remains the most-watched half-hour sitcom episode.
