The first half of the Twentieth Century saw the biggest explosion in monster stories. First in the Pulps and the movies, then television, children's books, comic books and paperbacks. Monsters are everywhere! Audiences discovered many of the creatures from the past for the first time on the silver screen and on little screens. Monsters are here to stay!
