"This is the witching hour! It is an hour when dogs howl, and evil things are let loose on a sleeping world. Want to hear about it? Then turn out your lights!"

Lights Out debuted in 1934 and was radio's premier horror series. Director and writer, Wyllis Cooper's writing was characterized by grisly stories always matched with the appropriate acting and sound effects, he conceived in 1933 the idea of writing a dramatic midnight mystery serial catchy enough to the listeners' attention at a time when the competition was mostly airing music. It was however dropped in favor of an anthology emphasizing crime thrillers and the supernatural. He stayed with this program until June 1936 when another Chicago writer, Arch Oboler, took over. By the time Cooper left, the series had inspired about 600 fan clubs.

Arch Oboler was eccentric and ambitious when he took over and picked up where Cooper left off, following the latter's general example but investing the scripts with his own concerns using streams of conscious narration and sometimes social and political themes that reflected his commitment to anti-fascist liberalism. Although Lights Out would be closely associated with Oboler later on, he would always credit Wyllis Cooper as the series' creator and spoke highly of him as "the unsung pioneer of radio dramatic techniques" and the first person he knew who understood that radio drama is an art form.

"Burial Service", Oboler's first script in 1936, was initially flooded with outraged response but was followed with the more accepted and frequently repeated "Catwife" and Caligula-inspired "The Dictator". This set the pattern for Oboler's run of two horror episodes followed by a drama on more serious subjects dealing with moral, social and political issues Click here to read more about Lights Out
