Some believe that the show is a rehashing of Boston's American Broadcasting Company affiliate WCVB's locally produced 1979 sitcom "Park Street Under" featuring Steve Sweeney and American Repertory Theater founder Karen MacDonald. Three men developed and created the "Cheers" television series: Glen and Les Charles ("Glen and Les") and James Burrows, who identified themselves as "two Mormons and a Jew." They aimed at "creating a show around a Spencer Tracy-Katharine Hepburn-type relationship" between their two main characters, Sam and Diane. Malone represents the average man, while Chambers represents class and sophistication. The show revolves around characters in a bar under "humorous adult themes" and "situations."
