Jack Armstrong began on July 31, 1933, created by Robert Hardy Andrews to sell Wheaties. Jack, a Hudson High athlete, traveled the world with his friends Billy and Betty Fairfield and their Uncle Jim, in fifteen-minute chapters every weekday. Jim Ameche played Jack until 1938, and Michael Rye was among those who followed. The show lasted until 1951, at the end as Armstrong of the SBI.
