Early 80s also had a few five-a-day-syndies: Family Feud, (nose hold) 3's a Crowd, To Tell the Truth, Match Game. Match Game was off by '79, but CBS' number is still right (just replace Match Game with Whew!)
1975 was probably the biggest single year, which each of the networks usually having six daytime games:
NBC-Celebrity Sweepstakes, Wheel, High Rollers, Squares, Jackpot, Blank Check
CBS-Joker's Wild, Gambit, Now You See It, Match Game, Price, Tattletales
ABC-Blankety Blanks, Password, Split Second, Pyramid, Let's Make a Deal, Newlywed Game
Syn (daily)-Truth or Consequences, To Tell the Truth
You also had Dealer's Choice and Concentration in a good part of the country on five-day-a-week syndication, LMAD/Squares on two-day-a-week, and Name That Tune, Match Game, Sweepstakes, Price is Right, Pyramid, Treasure Hunt, Masquerade Party and Jeopardy on once-a-week. And because of some stations really on the late end of the bicycling, Beat the Clock and What's My Line could still be seen in a handful of places.
