Saturn was an American magazine published from 1957 to 1965. It was launched as a science fiction magazine, but sales were weak, and after five issues the publisher, Robert C. Sproul, switched the magazine to hardboiled detective fiction that emphasized sex and sadism. Sproul retitled the magazine Saturn Web Detective Story Magazine to support the change, and shortened the title to Web Detective Stories the following year. In 1962, the title was changed yet again, this time to Web Terror Stories, and the contents became mostly weird menace tales—a genre in which apparently supernatural powers are revealed to have a logical explanation at the end of the story.
