The television series that made stars out of John Ritter (who was nominated for three Emmys) and Suzanne Somers, THREE'S COMPANY has been a mainstay of television, both during its initial run and in syndication, every since it first premiered. Its formula of slapstick comedy, racy double entendres, and comic misunderstandings is well-known to millions of viewers. SEASON FOUR collects all 25 episodes that aired during the 1979-1980 season, when the show was routinely number one or two in the ratings. This season was also the first with Don Knotts as landlord Ralph Furley, replacing the Ropers, who had been granted their own spin-off sitcom. THREE'S COMPANY was massively popular during its initial eight season run, and has since become a television landmark.
