Famous Monsters of Filmland was originally conceived as a one-shot publication by Warren and Ackerman, published in the wake of the widespread success of the package of old horror movies syndicated to American television in 1957. But the first issue, published in February 1958, was so successful that it required a second printing to fulfill public demand. Its future as part of American culture was immediately obvious to both men. The success prompted spinoff magazines such as Spacemen, Famous Westerns of Filmland, Screen Thrills Illustrated, Creepy, Eerie, and Vampirella.In the pages of FM, Forrest J Ackerman promoted the memory of Lon Chaney, Sr., whose silent works were mostly beyond the accessibility of fans for most of the magazine’s life, but were a great influence on his own childhood. He also introduced film fans to science fiction fandom through direct references, first-person experiences, and adoption of fandom terms and customs.
