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.

Rodman Edward Serling was an American screenwriter and television producer best known for his live television dramas of the 1950s and his anthology television series The Twilight Zone. Serling was active in politics, both on and off the screen, and helped form television industry standards. He was known as the "angry young man" of Hollywood, clashing with television executives and sponsors over a wide range of issues, including censorship, racism, and war.
