In over 6,500 episodes, she has apparently never worn the same gown twice. White, who operates the board and reveals letters as they are guessed, often contributes her own puzzles to the show. Sajak and White, who joined in 1981 and 82, respectively, have become some of the most famous hosts in game show history. The phrases 'I'd like to buy a vowel' and 'I'd like to solve the puzzle' have entered the American cultural lexicon.
Since the show's inception, the price of a vowel has stood at $250 and has not been adjusted for inflation. Contestants guess letters as they attempt to solve a Hangman-like puzzle, spinning the wheel to determine how much money they will earn for a correct guess, with the ultimate goal being to solve the puzzle and accumulate as much money as possible. Griffin, who had already created another iconic game show, Jeopardy!, conceived of Wheel as a combination between Hangman and roulette. Created by television legend Merv Griffin and hosted since the early 1980s by Pat Sajak and Vanna White, Wheel is one of the most popular television shows in the world. Wheel of Fortune, one of the the longest-running syndicated game show in American television, premieres on NBC on January 6, 1975.
