I went on a bingewatch of the final season. It wasn't so much drunkenness that stuck out to me, it was how "checked out" everyone was. The moment that sticks out to me is one that involves Brett. With about nine weeks to go, there was an episode that opens with "Get ready to match the stars..." and when Johnny announces Brett Somers, Brett's chair is empty. "As we play the star-studded big-money Match Game!" The set lights up, and Brett is crossing the stage with a cup in her hands and heading to her seat. Wasn't a bit or anything--she just wasn't there when tape started rolling and nobody CARED.
One possibility is that someone decided they weren't going to let the problems they were having on
Feud, with tapings running long because of Richard Dawson, repeat on their other shows.
By that point, I suspect everybody knew the end was near.
Match Game PM had ended, and I'm sure the show was getting weaker time slots -- at that point most markets certainly had
Family Feud and then-hot
Tic Tac Dough in prime access, and the one station that didn't probably ran something like
PM Magazine as counterprogramming (or
Entertainment Tonight, which was new that year). In New York,
Match Game moved from 4:30 PM on WCBS in 1980 to 6:30 PM on WOR (the weakest of the independent stations) in 1981 -- but by November had already been moved to 2:30 PM (in favor of
The New You Asked For It).
Hollywood Squares had gone through the same thing the previous year -- Peter Marshall noted in his book that when he needed help from Jay Redack and Bob Quigley, they were at the blackjack tables and couldn't be found, because the assumption was the rest of the staff could handle anything by themselves. (And if people were upset by Dawson not smiling in his final days on
MG, look at Paul Lynde during some of the opens before the show logo appears.)
It's a shame the people in front of the camera felt this way, although it's understandable—after nine years or more, it's like being at a party that's gone on too long, and a few people are obviously looking to leave. But for the people who did the production work, it had to be frustrating knowing your job was coming to an end.
EDIT: I vaguely recall somebody saying here that in 1981, MGP considered moving
Match Game tapings from CBS to Merv Griffin's Trans-American Video theater as a cost-cutting move, but it turned out the
MG set wouldn't fit on Merv's stage. Can someone verify?
