Three's a Crowd (also known as Three's Company, Too in the Three's Company syndication package) is an American sitcom television series produced as a spin-off continuation of Three's Company that aired on ABC from September 25, 1984 (only one week after the final episode of Three's Company was broadcast) until April 9, 1985, with reruns airing until September 10, 1985. It is loosely based on the British sitcom Robin's Nest, which was itself a spin-off of Man About the House, upon which Three's Company was based. Plot In Three's Company's final episodes, Vicky Bradford (Mary Cadorette) is introduced as a love interest of Jack Tripper (John Ritter), beginning with the episode titled "Cupid Works Overtime." In the following two-part episode, "Friends and Lovers", Jack proposes marriage, but Vicky, afraid of marriage after witnessing her parents' tumultuous relationship and bitter divorce, declines the offer. Vicky instead convinces Jack to move in with her in the vacant apartment above his restaurant. Vicky's wealthy father James Bradford (Robert Mandan) buys the building from Jack's former boss, Frank Angelino. James does not approve of Jack and he constantly tries to disrupt his and Vicky's relationship. Other characters include E.Z. Taylor (Alan Campbell), Jack's eccentric assistant at the bistro, and Claudia Bradford (Jessica Walter), Vicky's mother and James' ex-wife.

Taylor Recurring Jessica Walter as Claudia Bradford Production history Three's Company had been based on the sitcom Man About the House, which aired on ITV in the United Kingdom from 1973 to 1976. When the series concluded, producers Brian Cooke and Johnnie Mortimer devised two spin-offs. The first was George and Mildred, which ran from 1976 to 1979 and starred Brian Murphy and Yootha Joyce as their George and Mildred Roper characters. The second spin-off was Robin's Nest, which ran from 1977 to 1981 and featured Richard O'Sullivan as Robin Tripp (the basis of the Jack Tripper character), who runs the titular restaurant along with his live-in girlfriend and her antagonistic father. Three's Company's producers were eager to capitalize on these spin-offs. In 1979, they had spun off The Ropers, based on George and Mildred, but the show ran for only one and a half seasons. Executive producers Ted Bergmann and Don Taffner attempted to adapt the Robin's Nest series, but without John Ritter.
