Night Gallery is an American anthology television series that aired on NBC from December 16, 1970, to May 27, 1973, featuring stories of horror and the macabre. Rod Serling, who had gained fame from an earlier series, The Twilight Zone, served both as the on-air host of Night Gallery and as a major contributor of scripts, although he did not have the same control of content and tone as he had on The Twilight Zone. Serling viewed Night Gallery as a logical extension of The Twilight Zone, but while both series shared an interest in thought-provoking dark fantasy, more of Zone's offerings were science fiction while Night Gallery focused on horrors of the supernatural.

The Twilight Zone is an American fantasy science fiction horror anthology television series created and presented by Rod Serling, which ran for five seasons on CBS from October 2, 1959, to June 19, 1964. Each episode presents a standalone story in which characters find themselves dealing with often disturbing or unusual events, an experience described as entering "the Twilight Zone", often with a surprise ending and a moral. Although often considered predominantly science-fiction, the show's paranormal and Kafkaesque events leaned the show much closer to fantasy and horror. The phrase "twilight zone" has entered the vernacular, used to describe surreal experiences.
