The first specialized English-language pulps with a leaning towards the fantastic were Thrill Book (1919) and Weird Tales (1923), but the editorial policy of both was aimed much more towards weird-occult fiction than towards sf.
Web-based magazines tend to favor shorter stories and articles that are easily read on a screen, and many of them pay little or nothing to the authors, thus limiting their universe of contributors.
The first science fiction magazine,[5] Amazing Stories, was published in a format known as bedsheet, roughly the size of Life but with a square spine.
The premiere issue of Amazing Stories (April 1926), edited and published by Hugo Gernsback, displayed a cover by Frank R. Paul illustrating Off on a Comet by Jules Verne.
Much fiction published in these bedsheet magazines, except for classic reprints by writers such as H. G. Wells, Jules Verne and Edgar Allan Poe, is only of antiquarian interest.
Some of the stories in the early issues were by scientists or doctors who knew little or nothing about writing fiction, but who tried their best, for example, David H. Keller.
Probably the two best original sf stories ever published in a bedsheet science fiction magazine were "A Martian Odyssey" by Stanley G. Weinbaum and "The Gostak and the Doshes" by Miles Breuer, who influenced Jack Williamson.
There have been a few unsuccessful attempts to revive the bedsheet size using better quality paper, notably Science-Fiction Plus edited by Hugo Gernsback (1952–53, eight issues).
Isaac Asimov's Foundation Trilogy and Robert A. Heinlein's Future History in the 1940s, Hal Clement's Mission of Gravity in the 1950s, and Frank Herbert's Dune in the 1960s, and many other science fiction classics all first appeared under Campbell's editorship.
Pulp science fiction is known for clichés such as stereotypical female characters, unrealistic gadgetry, and fantastic monsters of various kinds.

Under the editorship of Cele Goldsmith, Amazing and Fantastic changed in notable part from pulp style adventure stories to literary science fiction and fantasy.
[19] There was also no shortage of digests that continued the pulp tradition of hastily written adventure stories set on other planets.
A Canticle for Leibowitz, written by Walter M. Miller, Jr., was first published in The Magazine of Fantasy & Science Fiction.
