The ad agency Dancer-Fitzgerald-Sample (and later Saatchi & Saatchi) used "Bullwinkle" and other kid shows in syndication to promote their clients exclusively.
Didn't General Mills also have a hand early on in "The Program Exchange" (the DFS / S&S syndication company)?
I shudder to think how contrived the scripts must have been on a show called Police Surgeon, unless it was a poorly named predecessor of Quincy, M.E.
According to the Brooks / Marsh TV "Directory", Police Surgeon and (especially) its predecessor, "Dr. Simon Locke", was produced very cheaply, in terms of bad lighting, not screening shows to the stars until they were complete, bad editing and poorly-hacked scripts, plus special guest appearances by overhead mikes. And in on-location work, actors found themselves changing in the bushes, instead of a trailer. One of the stars for the show's first season, Jack Albertson (previously of "Willy Wonka", later of "Chico and the Man") quit, to save his reputation, even though he was under contract.
The show got made, mainly due to the new (at the time) Prime Time Access Rule in the US and CanCon rules in Canada (where the show was filmed). It also gave Colgate an opportunity to give the show to stations for free, in exchange for showing some Colgate-Palmolive spots in the show.
Despite the abyssimal reviews, "Police Surgeon" lasted in first-run syndication under Colgate for 3 years, and continued in repeats (under another syndicator) through the late-1970s. The show was even internationally-syndicated to countries such as Japan.
Nevertheless, "Police Surgeon" has set the standard (as low as possible) for Tv programs produced in Canada.
