The Zero Hour (aka Hollywood Radio Theater) was a 1973-74 radio drama anthology series hosted by Rod Serling. With tales of mystery, adventure and suspense, the program aired in stereo for two seasons. Some of the scripts were written by Serling.
Syndicated by the Mutual Broadcasting System, the series debuted September 3, 1973. The original format featured five-part dramas broadcast Monday through Friday with the story coming to a conclusion on Friday. Including commercials, each part was approximately 30 minutes long. Since Mutual affiliates could broadcast the programs at convenient timeslots on any suitable dates, the series did not begin in certain areas until late fall or early winter of 1973.
In 1974, still airing five days a week, the program changed to a full story in a single 30-minute installment with the same actor starring throughout the week in all five programs. That format was employed from late April 1974 to the end of the series on July 26, 1974.
