I haven't hunted for the article yet, but if it's the show I'm thinking of ("Who Knows?" IIRC), it was a bluffing game along the lines of "Wordplay".
Close. Who Knew? was the title and Paramount was on board to produce/distribute.

e other series it was responsible for didn't last more than a year, right?
