Man, this thread brings back a lot of memories, having seen a handful of these shows, like Telequest, Alumni Fun, and Tell Me Something Good. Some other awfully obscure ones come to mind - an old satellite network ran The Shopping Game, hosted by Art James. A Nicholson-Muir production, this was one of the earliest shows to merge a game show with call and order shopping, before the Home Shopping Game later with Bob Goen. 4 players answered questions to build up a bankroll, which they would use to bid for the items that, after the bidding, would be offered to home viewers. The idea was, since none of the players knew how much money each other had, a player could attempt to bluff a bid, offering more than they had, to win the prize. IIRC, a player's bid could be challenged. Memory fades a bit from there. If I had two Holy Grail shows I'd like to see in this category, it would be Barry & Enrights "High-Low", and Ed Wolf's "Keep Talking". I believe a touch of video exists for both, as "Gilmore Box" has the High-Low open on You Tube, and another famous collector included a tiny clip of the Carl Reiner version in a montage of shows. There's hope. One more oldie comes to mind - a CBS Saturday afternoon kids quiz around the early to mid-60s following all the cartoon blocks called "Do You Know?" Had a vocal theme song.
