Origin of "warmedy"

[Paul McFedries]

I'm trying to trace the origin of the term "warmedy," a sitcom (or comedic
movie) that features warm-hearted, family-oriented content. The closest I've
come is the following hint:

The 'creative team' that set out in the fall of 1978 to put Shirley
together began with commensurate ambitions. The show was to be at once
witty, happily emotional, and dramatic -- a sort of classy example of
the genre that one TV Critic has dubbed 'warmedy.'
--Walter Kiechel III, Fortune, December 31, 1979

Does anyone have any idea who the above-mentioned "TV Critic" is?

Thanks.

Paul
