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.[10] Three men developed and created the Cheers television series: Glen and Les Charles ("Glen and Les") and James Burrows,[11] who identified themselves as "two Mormons and a Jew."[12] They aimed at "creating a show around a Spencer Tracy-Katharine Hepburn-type relationship" between their two main characters, Sam and Diane.[11] Malone represents the average man, while Chambers represents class and sophistication.[11] The show revolves around characters in a bar under "humorous adult themes" and "situations."[11]
