Horror comic books reached a peak in the late 1940s through the mid-1950s, when concern over content and the imposition of the self-censorship Comics Code Authority contributed to the demise of many titles and the toning down of others. Black-and-white horror-comics magazines, which did not fall under the Code, flourished from the mid-1960s through the early 1980s from a variety of publishers. Mainstream American color comic books experienced a horror resurgence in the 1970s, following a loosening of the Code. While the genre has had greater and lesser periods of popularity, it occupies a firm niche in comics as of the 2010s.
Precursors to horror comics include detective and crime comics that incorporated horror motifs into their graphics, and early superhero stories that sometimes included the likes of ghouls and vampires. Individual horror stories appeared as early as 1940. The first dedicated horror comic books appear to be Gilberton Publications' Classic Comics #13 (Aug. 1943), with its full-length adaptation of Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde, and Avon Publications' anthology Eerie #1 (Jan. 1947), the first horror comic with original content. The first horror-comics series is the anthology Adventures into the Unknown, premiering in 1948 from American Comics Group, initially under the imprint B&I Publishing.
