Lights Out, a 15 minute program (later expanded to 30min.) created by Wyllis Cooper, was a classic horror radio show that spanned from the mid 30's to the late 40's. Cooper was a great horror writer, but he moved to Hollywood in 1936 to try his hand at script writing for the big screen. Cooper wrote Son Of Frankenstein and other screenplays, but nothing compares to his original radio shows. Arch Oboler took over and Lights Out grew into a household name. Obler's plots included a "Chicken Heart" that ate the world, or in the case of "Meteor Man," a large alien's head that consumed human beings.
By 1938, he also left the show to write anti-Nazi propaganda for a series called Arch Olber's Plays. Lights Out continued for another year with alternate NBC writers and directors. Then Oboler came back in 1942 and became the host, with a new announcer, Bob LeMond.
