Rod Serling created & hosted the CBS tv series 10-2-59 to 9-5-65, with the exception of the 1 hour pilot, which was hosted by Desi Arnaz (a story in which the subject kept waking up in a Pearl Harbor waterfront bar on 12-7-41, but couldn't get anyone to believe him: not bartender Jesse White in 1941 or psychiatrist Martin Balsom in the present), and is not seen on the Sci-Fi channel (TV Land has exclusive rights). Though Ray Bradbury was not credited for it, one of his novels was adapted for a classic episode in which a man is on trial for not turning in his books to be burned as ordered by a government.
All the other episodes were half hour with the exception of 1963 when CBS tried hour-long episodes. But the fans seemed to prefer the more concentrated writing and suspense of 30 minutes and the series returned to half-hour stories the remaining 2 years. When Twilight Zone ended its run in 1965, Serling went on to other projects and CBS assigned the writers & directors to a new science fiction-western project called Wild Wild West. When West ended its run in 1970, Rod Serling needed them back for a new series on NBC called Night Gallery starting with a 3-segment Night Gallery movie.
