Fantastic Story Magazine

Fantastic Story Quarterly was a pulp science fiction magazine, published from 1950 to 1955 by Best Books, a subsidiary imprint of Standard Magazines. The name was changed with the Summer 1951 issue to Fantastic Story Magazine. It was launched to reprint stories from the early years of the science fiction pulp magazines, and was initially intended to carry no new fiction, though in the end every issue contained at least one new story. It was sufficiently successful for Standard to launch Wonder Story Annual as a vehicle for more science fiction reprints, but the success did not last. In 1955 it was merged with Standard's Startling Stories. Original fiction in Fantastic Story included Gordon R. Dickson's first sale, "Trespass", and stories by Walter M. Miller and Richard Matheson.

The first science fiction (sf) magazine, Amazing Stories, was launched in 1926 by Hugo Gernsback at the height of the pulp magazine era. It helped to form science fiction as a separately marketed genre, and by the mid-1930s several more sf magazines had appeared, including Wonder Stories, also published by Gernsback. In 1936, Ned Pines of Beacon Publications bought Wonder Stories from Gernsback. Pines changed the title to Thrilling Wonder Stories, and in 1939 and 1940 added two more sf titles: Startling Stories and Captain Future. Pines had acquired reprint rights to the fiction published in Wonder Stories as part of the transaction, and he instituted a "Hall of Fame" department in Startling Stories to carry some of this material. Captain Future also carried reprint material, but neither Startling nor Captain Future had room for some of the longer stories in the backfile. At the end of the 1940s a boom in science fiction magazines encouraged Pines to issue a new magazine, titled Fantastic Story Quarterly, as a vehicle for reprinting this older material. The original plan was for the magazine to carry no new fiction, but this policy was changed shortly before publication, and at least one new story was included in every issue.
