Merv Griffin conceived Wheel of Fortune just as the original version of Jeopardy!, another show he had created, was ending its 11-year run on NBC with Art Fleming as its host. Griffin decided to create a Hangman-style game after recalling long car trips as a child, on which he and his sister played Hangman. After he discussed the idea with Merv Griffin Enterprises' staff, they thought that the idea would work as a game show if it had a "hook". He decided to add a roulette-style wheel because he was always "drawn to" such wheels when he saw them in casinos. He and MGE's then-president Murray Schwartz consulted an executive of Caesars Palace to find out how to build such a wheel.
