Analog Science Fiction and Fact is an American science fiction magazine that is still produced today. As of 2015, it is the longest running continuously published magazine of the genre. Initially published in 1929 as Astounding Stories, it has undergone several name changes, primarily to Astounding Science-Fiction in 1938, and Analog Science Fact & Fiction in 1960. Spanning three incarnations since 1930, this is perhaps the most influential magazine in the history of the genre.

When the magazine’s long-standing editor John W. Campbell, Jr. died in 1971, he was replaced by Ben Bova, and unsurprisingly, the magazine gained considerably in vitality through having a new editor after nearly 34 years. While the editorial policy remained oriented towards traditional SF, a more liberal attitude prevailed. The range of artists was also widened with the addition of Jack Gaughan and the discovery of Rick Sternbach and Vincent Di Fate. In 1978, Stanley Schmidt took over as editor and embarked on a Campbell-equalling feat of 34 years in charge of the magazine.

Award winning stories that have appeared in Analog include: Dune World, which was expanded into the novel Dune (Frank Herbert); Dragonrider  (Anne McCaffrey); The Gold at the Starbow's End (Frederik Pohl); Hero, opening the serialization of The Forever War (Joe Haldeman); The Hole Man (Larry Niven);  Home is the Hangman (Roger Zelazny);  By Any Other Name (Spider Robinson);  The Saturn Game (Poul Anderson); Blood Music (Greg Bear); Good (Isaac Asimov); The Missing Man (Katherine MacLean).
