pulp magazine

Pulp magazines, also called "the pulps", were inexpensive fiction magazines that were published from 1896 until around 1955. The word pulp derives from the cheap wood pulp paper on which the magazines were printed. In contrast, magazines printed on higher-quality paper were called "glossies" or "slicks". The typical pulp magazine was 128 pages in length, 7 by 10 in (18 by 25 cm), and 0.5 in (1.3 cm) thick, with ragged, untrimmed edges. Pulps were the successors to the penny dreadfuls, dime novels, and some of the short-fiction magazines of the 19th century.

Although many respected writers wrote for pulps, the magazines were best known for their lurid, exploitative, and sensational subject matter, even though this was but a small part of what existed in the pulps. Digest magazines and men's adventure magazines were incorrectly regarded as pulps, though they have different editorial and production standards and are instead replacements. Modern superhero comic books are sometimes considered descendants of "hero pulps"; pulp magazines often featured illustrated novel-length stories of heroic characters, such as Flash Gordon, The Shadow, Doc Savage, and The Phantom Detective.
