It's amusing to me the 1970s CBS episodes, which were famous for pushing the content envelope, seem to be much less edited today than the 1980s NBC shows, which have very few salacious questions.
Yeah, I’ve noticed there seems to be an “innocence bias,” I guess, toward the 70s shows. Besides the lighter-touch editing, BUZZR generally gives 70s shows, including Match Game, a TV-G rating, while being quicker to slap a TV-PG on 80s & later shows. There’s certainly a debate to be had over whether the TV content ratings are worth a darn in the first place, but I really don’t know how one can say 70s MG is totally G-rated, particularly when giving MGHSH a (justified, IMO) PG rating. I don’t know; maybe it’s a bias that shows were more innocent in the “good old days.”
