Overview
100 Grand is an American game show hosted by Jack Clark. The series ran for three episodes, weekly on Sunday nights from September 15 to 29, 1963.
Broadcast on Sundays from 10 to 10:30 p.m. Eastern Time, 100 Grand was the first "big money" show to be broadcast after the quiz-show scandals in 1958.
Game play
Two people, one an expert in a given field and the other an amateur interested in that field, were paired. Each contestant had to answer questions that the other had created. The questioning took place in an isolation booth. Before the session, two "authenticating judges" evaluated the questions to "be sure that they are absolutely correct according to several reference works and that they conform to the rules in a 199-page instruction book".
The player who stumped the professional for five weeks, had the show survived that long, would have had the privilege to answer five questions submitted by home viewers, and ended up with a grand total of $100,000 if successful.
