Two things that interested me about that article...
1) the use of the phrase "reality TV" as early as 1982, and
2) 41 half-hours* (1981-82 season) being considered a low point. With games considered popular again, there's roughly the same amount of half-hours on now (Wheel/J! is 10 per week, then double runs of the other five shows is 50, so 60 half-hours).
I think that's right. Too much math, my head hurts.
*I'm guessing that made for eight daily games (40 hrs.), and one weekly: a) Feud, b) Joker, c) Tic Tac d) Treasure Hunt e) Pitfall f) Super Pay Cards, g) Bullseye, h) Match Game, and one more that I can't recall. Or something like that...
