Three's Company is an American television sitcom that aired for eight seasons on ABC from March 15, 1977, to September 18, 1984. Developed by Don Nicholl, Michael Ross and Bernie West, it is based on the British sitcom Man About the House created by Brian Cooke and Johnnie Mortimer.

The story revolves around three single roommates: Jack Tripper, Janet Wood, and Chrissy Snow, who all platonically live together in a Santa Monica, California apartment complex owned by Stanley and Helen Roper. The show, a farce, chronicles the escapades and hi jinks of the trio's constant misunderstandings, social lives, and financial struggles. A top 10 hit from 1977 to 1983, the series has remained popular in syndication and through DVD releases. The show also spawned similar spin-offs to those that Man About the House had: The Ropers and Three's a Crowd, based upon George and Mildred and Robin's Nest, respectively.
