American science fiction and fantasy magazines flourished from the mid-1920s to the 1940s. The first magazine to focus on fantasy and horror was Weird Tales, launched in 1923, which established itself as the leading weird fiction magazine over the next two decades, with regular contributors such as H. P. Lovecraft, Clark Ashton Smith and Robert E. Howard. In 1926 Hugo Gernsback's Amazing Stories appeared (pictured), running only science fiction. Its letters column, which often provided contact information, marked the beginning of organized science fiction fandom. Astounding Stories of Super-Science, founded in 1930, became the leading magazine in its genre, publishing early classics such as Murray Leinster's "Sidewise in Time". John W. Campbell took over as editor in 1937 and ran works by Robert A. Heinlein, Isaac Asimov, and A. E. van Vogt. Only eight science fiction and fantasy magazines survived World War II, with all but Astounding still in pulp magazine format.
