The Wizard of Odds is an American television game show hosted by Alex Trebek that aired on NBC from July 17,1973, to June 28, 1974, in which people from the studio audience vied in a number of rounds, primarily games revolving around statistical questions. John Harlan announced the pilot; Los Angeles radio personality Sam Riddle was the show's first announcer; towards the end of the run, Charlie O'Donnell replaced him. The title was a parody of the classic 1939 movie The Wizard of Oz and was the first American game show Trebek hosted.
