Thanks for posting the link.
The article includes examples of some of the questions asked on "Jeopardy!" and "The Who, What or Where Game." One of the "Jeopardy!" questions seems unfair in my opinion, and I'm surprised that NBC standards allowed it:
Category: World Geography. "The only country in the world whose name begins and ends with the same consonant."
The first possible answer I thought of was Seychelles, but that wasn't an independent country in 1970. I also thought of Czech Republic, but I knew that didn't become an independent country until the 1990s.
The answer: Tibet. But that wasn't an independent country in 1970, either.
In the first place, "NBC Standards" wasn't responsible for researching and fact-checking the material. They're just there to make sure the games are played without cheating.
Secondly, the rigorous standards that we associate with the current Jeopardy didn't exist back then. Sure, they wanted to get it right, and the game was as much of an intellectual challenge then as it is now (not dramatically more so, as some critics continue to insist today), but they didn't have fleets of researchers poring over every detail of every clue. Even some of the accurate material back then would be considered sloppily written by today's stricter rules. And of course, the 70s writers had access to reference
books, but not the web of the wide world at their fingertips like we do now.
Plus, we don't know how that particular episode played out. Maybe if a contestant was wronged over the clue, they got to come back and play again.
