Adventures Into the Unknown was an American comic-book magazine series best known as the medium's first ongoing horror-comics title. Published by the American Comics Group, initially under the imprint B&I Publishing, it ran 174 issues (cover-dated Fall 1948 - Aug. 1967). Unlike many American horror comics of the Golden Age, it weathered the public criticism of the early 1950s and survived the aftermath of the Senate Subcommittee on Juvenile Delinquency hearings of April and June 1954 when the comics industry attempted self-regulation with a highly restrictive Comics Code.
