An American comic book is a thin periodical originating in the United States, on average 32 pages, containing comics. While the form originated in 1933, American comic books first gained popularity after the 1938 publication of Action Comics, which included the debut of the superhero Superman. This was followed by a superhero boom that lasted until the end of World War II. After the war, while superheroes were marginalized, the comic book industry rapidly expanded and genres such as horror, crime, science fiction and romance became popular. The 1950s saw a gradual decline, due to a shift away from print media in the wake of television and the impact of the Comics Code Authority. The late 1950s and the 1960s saw a superhero revival and superheroes remained the dominant character archetype throughout the late 20th century into the 21st century.

Bandes dessinées, abbreviated BDs and also referred to as Franco-Belgian comics, are comics that are usually originally in French and created for readership in France and Belgium. These countries have a long tradition in comics, separate from that of English-language comics. Belgium is a mostly bilingual country, and comics originally in Dutch are culturally a part of the world of bandes dessinées, even if the translation from French to Dutch far outweighs the other direction.
