+ Jack Armstrong, the All-American Boy was a radio adventure series which maintained its popularity from 1933 to 1951. The program originated at WBBM in Chicago on July 31, 1933, and was later carried on CBS, then NBC and finally ABC. The storylines centered around the globe-trotting adventures of Armstrong (played by Jim Ameche until 1938), a popular athlete at Hudson High School, his friends Billy Fairfield and Billy's sister Betty, and their Uncle Jim, James Fairfield, an industrialist. Frequently, Uncle Jim Fairfield would have to visit an exotic part of the world in connection with his business, and he would take Jack Armstrong and the Fairfield siblings along with him. Many of the adventures provided listeners with the equivalent of a travelogue, providing facts about the lands they were visiting. The show was created by writer Robert Hardy Andrews. Sponsored throughout its long run by Wheaties, the program was renamed Armstrong of the SBI when Jack graduated high school and became a government agent in the final season, when it shifted from a 15-minute serial to a half-hour complete story format. Throughout its broadcast span, the program offered radio premiums that usually related to the adventures in which Jack and his friends were involved.-WikiPedia Click here to read more about Jack Armstrong
