 When the show first began there were only three people on the panel  and the top prize was $75. The panelists who ran out of questions or  didnt make the correct guess paid the contestant a check for $25.  However, in 1954, the panel expanded to the more familiar four  person set up that was used on "Whats My Line" and "Ive Got a  Secret" and the top prize went up to $80 and each panelist who  didnt make a correct guess or ran out of questions now paid $20.
