Dear John is an American sitcom that aired on NBC from 1988 to 1992. The series was originally based on the British sitcom of the same name. Dear John was retitled Dear John USA when it was shown in the UK. During its four-season run, the series was bounced to and from various time periods on Wednesday, Thursday, Friday, and Saturday nights. When the series moved from its post-Cheers slot on Thursdays to a post-Night Court slot on Wednesdays in 1990, series regular Jere Burns appeared in a network promo side-by-side with John Larroquette of Night Court.
Reruns were syndicated to various local stations shortly after Dear John ended its run in 1992, which continued until 2004. The series also aired on E! for a brief period in the late-1990s. The show has not been seen in the United States since it left syndication.
