‘The Shadow’ makes His First Appearance on Radio
"Who knows what evil lurks in the hearts of men? The Shadow knows!" was the opening line to The Shadow radio program spoken by actor Frank Readick Jr. The Shadow was a collection of serialized dramas originally published as pulp novels. On this day in 1930, the Shadow aired his first radio show, which was followed by a magazine series, comic books, comic strips, television, serials, video games, and at least five motion pictures.
