Superhero comics in the context of "Action Comics 1"

Pulp magazines (also referred to as "the pulps") were inexpensive fiction magazines that were published from 1896 until around 1955. The term "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, 7 inches (18 cm) wide by 10 inches (25 cm) high, and 0.5 inches (1.3 cm) thick, with ragged, untrimmed edges. Pulps were the successors to the penny dreadfuls, dime novels, and 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.

Batman is an ongoing superhero comic book series published by DC Comics, featuring the character of the same name as its protagonist. The character, created by Bill Finger and Bob Kane, first appeared in Detective Comics #27 (cover dated May 1939). Batman proved to be so popular that a self-titled ongoing comic book series began publication with a cover date of spring 1940. It was first advertised in early April 1940, one month after the first appearance of his new sidekick, Robin the Boy Wonder. Batman comics have proven to be popular since the 1940s.

Though the Batman comic book was launched as a quarterly publication, it later became a bimonthly series through the late 1950s, after which it became a monthly publication.

Stan Lee (born Stanley Martin Lieber /ˈliːbər/; December 28, 1922 – November 12, 2018) was an American comic book writer, editor, publisher and producer. He rose through the ranks of a family-run business called Timely Comics which later became Marvel Comics. He was Marvel's primary creative leader for two decades, expanding it from a small publishing house division to a multimedia corporation that dominated the comics and film industries.

In collaboration with others at Marvel – particularly co-plotters and artists Jack Kirby and Steve Ditko – he co-created iconic characters, including Spider-Man, the X-Men, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, the Scarlet Witch, and Black Widow. These and other characters' introductions in the 1960s pioneered a more naturalistic approach in superhero comics. In the 1970s, Lee challenged the restrictions of the Comics Code Authority, indirectly leading to changes in its policies. In the 1980s, he pursued the development of Marvel properties in other media, with mixed results.
