The first season of the science fiction television series The X-Files commenced airing on the Fox network in the United States on September 10, 1993 and concluded on the same channel on May 13, 1994 after airing all 24 episodes.
The first season introduced main characters of the series, including Fox Mulder and Dana Scully who were portrayed by David Duchovny and Gillian Anderson respectively, and recurring characters Deep Throat, Walter Skinner and The Smoking Man. The season introduced the series’ main concept, revolving around the investigation of paranormal or supernatural cases, known as X-Files, by the Federal Bureau of Investigation; it also began to lay the groundwork for the series’ overarching mythology.
Initially influenced by Kolchak: The Night Stalker and The Twilight Zone, series creator Chris Carter pitched the idea for the series to Fox twice before it was accepted for production. The season saw the series quickly gaining popularity, with ratings rising steadily throughout its run; and garnered generally positive reviews from critics and the media. It helped to make stars of its two lead roles, and several of its taglines and catchphrases have since become cultural staples.
