Disliking arguments with Campbell over editorial decisions, after 1950 Sturgeon only published one story in "Astounding". Sturgeon wrote the screenplays for the ' episodes "Shore Leave" (1966) and "Amok Time" (1967, written up and published as a Bantam Books "Star Trek Fotonovel" in 1978). The latter featured the first appearance of pon farr, the Vulcan mating ritual, the sentence "Live long and prosper" and the Vulcan hand symbol. Sturgeon published the "first stories in science fiction which dealt with homosexuality, 'The World Well Lost' 1953 and 'Affair With a Green Monkey' 1957", and sometimes put gay subtext in his work, such as the back-rub scene in "Shore Leave", or in his Western story, "Scars". Sturgeon also wrote several episodes of ' that were never produced. One of these first introduced the Prime Directive. He also wrote an episode of the Saturday morning show "Land of the Lost", "The Pylon Express", in 1975. Two of Sturgeon's stories were adapted for "The New Twilight Zone". One, "A Saucer of Loneliness", was broadcast in 1986 and was dedicated to his memory. Another short story, "Yesterday was Monday", was the inspiration for "The New Twilight Zone" episode "A Matter of Minutes". His 1944 novella "Killdozer!" was the inspiration for the 1970s made-for-TV movie, Marvel comic book, and alternative rock band of the same name, as well as becoming the colloquial name for Marvin Heemeyer's 2004 bulldozer rage incident.
