Other NBC Burbank games (that I can think of) that regularly showed the audience:
You Don't Say! (during the intro)
Let's Make a Deal (well, of course)
Celebrity Sweepstakes
Mindreaders (audience game)
To Tell the Truth '90 (audience game)
Among East Coast NBC shows, Concentration often did pans of the audience at the midpoint of episodes.
OTOH, there were CBS shows that rarely or never seemed to show the audience -- Gambit (in the surviving episodes I've seen), Pyramid and Pass the Buck, to name a few. Now You See It sometimes showed the audience, but I don't recall Double Dare doing so. What about Whew?
