A workplace sitcom in the 60's wasn't always guaranteed to be a sure thing.
Such was the case with Many Happy Returns, which spent a season on CBS (1964-5), filling a vacancy on the schedule created when Danny Thomas ended his sitcom after 11 seasons. John McGiver top lined as Walter Burnley, head of a complaint department in a department store. Today, that would be known under a broader umbrella as customer service.
Now, I've never seen the show, so there won't be a rating. Anyway, CBS, undaunted, tried a department store comedy again nearly a decade later with James Coco in Calucci's Department, and that also lasted a season.
So why is that?
At the time, audiences were simply not ready for laughs in a consumer marketplace.
Here's the intro:
Co-star Mark Goddard moved on to Lost in Space the next year. Elena Verdugo would later turn up on Marcus Welby, MD. Elinor Donohue (ex-Father Knows Best, The Andy Griffith Show) didn't land another series, I think.
