The show’s main theme in its early seasons was the romance between the intellectual waitress Diane Chambers and bar owner Sam Malone, a former major league baseball pitcher for the Boston Red Sox and a recovering alcoholic. After Long left the show, the focus shifted to Sam’s new relationship with neurotic corporate climber Rebecca. Both relationships featured multi-episode “will they or won’t they” sexual tension that drew viewers in. After Sam and Diane’s courtship was consummated, the show’s popularity grew greatly and subsequent TV shows now very commonly have such “will they or won’t they” tensions between opposites.
