Lights Out is an American old-time radio program that originally aired from January 3, 1934, to the summer of 1947. Created by Wyllis Cooper and later taken over by Arch Oboler, the show featured horror and supernatural stories that evolved into crime thrillers and tamer ghost stories over time. Known for grisly stories and dark humor, the show utilized creative sound effects to intensify its horror aspects. Actors involved in the series included Sidney Ellstrom, Art Jacobson, Don Briggs, Bernardine Flynn, Betty Lou Gerson, and Betty Winkler. Cooper's version of Lights Out focused on atmospheric, supernatural tales, while Oboler delved deeper into psychological horror and occasionally explored political and social themes. The series was briefly revived in the mid-1940s using Cooper's original scripts, and it eventually transitioned to television.
