The Beverly Hillbillies The Clampetts Strike Oil.
The series is about a poor backwoods family transplanted to Beverly Hills, California, after striking oil on their land. A Filmways production created by writer Paul Henning, it is the first in a genre of “fish out of water” themed television shows, and was followed by other Henning-inspired country-cousin series on CBS. In 1963, Henning introduced Petticoat Junction, and in 1965 he reversed the rags to riches model for Green Acres. The show paved the way for later culture-conflict programs such as The Jeffersons, McCloud, The Nanny, The Fresh Prince of Bel-Air, and Doc. Panned by many entertainment critics of its time, it quickly became a huge ratings success for most of its nine-year run on CBS
