Three's Company is an American sitcom that aired from March 15, 1977, to September 18, 1984, on ABC. It is based on the British sitcom, Man About the House.

The story revolves around three single roommates: Janet Wood, Chrissy Snow and Jack Tripper who all platonically share Apartment 201 in a Santa Monica, California apartment building owned by Mr. and Mrs. Roper. Later, following Suzanne Somers's departure, Jenilee Harrison joined the cast as Cindy Snow (Chrissy's cousin), who was later replaced by Priscilla Barnes as Terri Alden. After the Ropers were spun-off into their own sitcom, Don Knotts joined the cast as Ralph Furley, brother of the new building owner.

The show, a comedy of errors, chronicles the escapades and hijinks of the trio's constant misunderstandings, social lives, and struggle to keep up with rent.

After crashing a wedding reception and finding himself passed out in the bathtub, cooking school student Jack Tripper meets Janet Wood, a florist, and Chrissy Snow, a secretary, in need of a new roommate. Having only been able to afford living at the YMCA, Jack quickly accepts the offer to move in.

Suzanne Somers (born as Suzanne Marie Mahoney on October 16, 1946) is an American actress, author, singer and businesswoman, known for her television roles as Chrissy Snow on Three's Company and as Carol Lambert on Step by Step.

Somers later became the author of a series of best-selling self-help books, including Ageless: The Naked Truth About Bioidentical Hormones (2006), a book about bioidentical hormone replacement therapy. She has also released two autobiographies, four diet books, and a book of poetry entitled "Touch Me" (1980). She currently features items of her design on ShopNBC.^{[citation needed]}

She is criticized for her views on some medical subjects and her advocacy of the Wiley Protocol, which has been labelled as "scientifically unproven and dangerous". Her promotion of alternative cancer treatments has received criticism from the American Cancer Society.

Born Suzanne Marie Mahoney in San Bruno, California, Somers was the third of four children in an Irish Catholic family. Her mother, Marion Elizabeth (née Turner), was a medical secretary, and her father, Francis Mahoney, was a laborer (loading beer into boxcars) and gardener. Her family attended church at St. Robert's Catholic Church in San Bruno.

Joyce Anne DeWitt (born April 23, 1949) is an American actress most famous for playing Janet Wood on the ABC sitcom Three's Company.

Joyce DeWitt, who is of no relation to actress Fay DeWitt, was born April 23, 1949 in Wheeling, West Virginia, and grew up in Speedway, Indiana, a suburb of Indianapolis. She is of Italian descent. She competed in speech and debate through the Indiana High School Forensic Association. After she received a bachelor's degree in theater from Ball State University, she moved to California to earn her master's degree from the University of California at Los Angeles (UCLA).

DeWitt began appearing on stage at the age of 13. While attending university, she worked as a secretary until her debut on Baretta. Contrary to reports, she has never painted actor Abe Vigoda's garage doors, and has never met the man. While performing in summer stock in the year following her graduation, a director and UCLA Theater professor convinced her to go to California for the school's MFA program.
