Tammy is an American sitcom. Manufactured by Universal City Studios, 26 colour off-the-shelf episodes were aired on ABC from September 17, 1965 to March 11, 1966. Tammy was broadly based on the three Tammy films. Tammy and the Bachelor. Tammy Tell Me True. And the Doctor and Tammy both starring Sandra Dee. The films were adaptations of books by Cid Ricketts Sumner. Other rural themed television sitcoms like the Beverly Hillbillies partially influenced the show. Specifically, there are similarities between Tammy's Cletus Tarleton and also The Beverly Hillbillies' Jethro Bodine.
