Once Mutual finished running the last of the Lewis-directed Jay Kholos episodes of The Zero Hour on March 14th, 1974, they went dark for six weeks. They were busy completely changing the format.

Now, one star would be featured in five different anthologies during a week. The show returned on April 29th. The first week’s star was Mel Torme. “Bye Bye Narco” was the first new script produced under Mutual’s umbrella.

“Rod Serling, master writer of the mysterious and macabre, is playing a game of suspense with the good earth. On the side, he serves as host of The Zero Hour, a weekday radio mystery series beamed by the Mutual Broadcasting System.

“Serling's feelings about the recent upsurge in radio drama prompted a call to his rural home. It soon became apparent that he is disappointed with radio drama and TV.

“Serling made it clear that he has nothing to do with the writing or producing of the twenty-five minute dramas. "I've caught the show about three times. One was passable and two I would have flunked off the air. What they're trying to do—and they may succeed—is a show that is contemporary. But it sounds campy.”

“Serling said, "The same thing applies to The CBS Radio Mystery Theater. It has to be relevant stuff for 1974. Short of that, why not resurrect old Shadow recordings? So far, I have yet to see either show relate to our time, either in story or technique. if they're selling us nostalgia, they've succeeded. It's thoroughly reminiscent of radio thirty years ago.”

“I'm not bad rapping it,” he said. “It's just not what I expected. I realize the economics of the situation. I wouldn’t want to spend my time writing a provocative radio drama and get a check that would buy me a carton of cigarettes. Radio drama currently has the value of an antique."

“Won't it change for the better? “I don't know," Serling said. “I have no idea. I'm frequently wrong, anyhow. I thought Nixon would be out of office by now. And I thought Sonny Liston would be heavyweight boxing champion for 20 years.”

“Summing up his feelings about radio and television, Serling said, “I feel the same way about radio as I do television as an art form. It doesn't rise to the occasion like it should...although television occasionally has.”

“Radio today is more of a display case than an art form.” — Raymond P. Hart

The Zero Hour in the new format ran thirteen additional weeks before being canceled after the July 26th, 1974, episode. In total, one-hundred-thirty episodes of The Zero Hour were produced. Most can be heard today.
