I've seen the 1974-75 revival of "Masquerade Party,"
with Richard Dawson as host, and Bill Bixby, Lee Meriwether,
and Nipsey Russell as panelists. I vaguely recall the Bert Parks
version around 1960, when I think Lee Bowman was a panelist,
but can't tell you how good a panelist he was.
I would also pick a very obscure 1967 ABC show called
"One In A Million," hosted by Danny O'Neill (who?). This
was one of Merv's disasters; contestants were given clues
to help them figure out which of five guests was "one in a
million," with some unusual claim to fame. Stick to "To Tell
The Truth."
And I'm surprised no one has mentioned two board games
which have failed to make the move to television: "Monopoly"
(ABC, 1980). Mike Reilly might have been a great "Jeopardy!"
contestant but he was badly out of his element as a host.
Besides, you can't play Monopoly in 30 minutes, and trying
to simplify it for television takes all of the fun out of it.
The other is "Trivial Pursuit." The Winker's version is better
left forgotten, and I don't understand the current version's
pitting a studio contestant against the whole country. This
is a game that could be simplified for television: have three
players, "Jeopardy!"-style; one picks a category, first player
to buzz in with a correct answer gets a wedge, six wedges
wins the game. If you want to know how a board game can
work on television, just look at Chuck Woolery's version of
"Scrabble" that lasted six years (1984-90).
