Produced by Filmways as a sister show to Petticoat Junction, the series was first broadcast on CBS, from September 15, 1965 to April 27, 1971. Receiving solid ratings during its six-year run, Green Acres was cancelled in 1971 as part of the "rural purge" by CBS. The sitcom has been in syndication and is available in DVD and VHS releases. In 1997, the two-part episode "A Star Named Arnold is Born" was ranked #59 on TV Guide's 100 Greatest Episodes of All Time.
