The Shadow debuted on July 31, 1930, as the mysterious narrator of the Street and Smith radio program Detective Story Hour.[4] After gaining popularity among the show's listeners, the narrator became the star of The Shadow Magazine on April 1, 1931, a pulp series created and primarily written by the prolific Gibson.

On September 26, 1937, The Shadow radio drama premiered with the story "The Deathhouse Rescue", in which The Shadow was characterized as having "the power to cloud men's minds so they cannot see him." As in the magazine stories, The Shadow was not given the literal ability to become invisible.

The introduction from The Shadow radio program "Who knows what evil lurks in the hearts of men? The Shadow knows!" spoken by actor Frank Readick Jr., has earned a place in the American idiom. These words were accompanied by an ominous laugh and a musical theme, Camille Saint-Saëns' Le Rouet d'Omphale ("Omphale's Spinning Wheel", composed in 1872). At the end of each episode The Shadow reminded listeners that, "The weed of crime bears bitter fruit. Crime does not pay... The Shadow knows!"
