The Zero Hour (U.S. radio series)

The radio series debuted on September 3, 1973, in syndication, and was picked up by the Mutual Broadcasting System in December.

Producer J. M. Kholos was a Los Angeles advertising man who acquired the rights to suspense novels, including Tony Hillerman's The Blessing Way, for radio adaptations.

To create a strong package, Kholos followed through by lining up top actors, including John Astin, Edgar Bergen, Joseph Campanella, Richard Crenna, John Dehner, Howard Duff, Keenan Wynn, Richard Deacon, Patty Duke, Nina Foch, George Maharis, Susan Oliver, Brock Peters and Lurene Tuttle.

Failing to find a large audience due to the initial weekly serial format and lack of promotion, Mutual canceled the program, and the final episode was broadcast on July 26 1974, though many Mutual affiliates continued broadcasting repeats for several months afterwards.
