Secret of the Yucatan Jungle - Jack Armstrong - The All-American Boy

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.

Jack Armstrong, the All-American Boy was a creation of General Mills, a pioneer in the development of unique and compelling advertising under the stewardship of Vice-president of Advertising, Samuel Chester Gale. Gale later served as President of the Ad Council. Intending to promote breakfast cereal Wheaties, Gale developed the character of Jack Armstrong as a fictitious "everyboy" whom listeners would emulate: If Jack ate Wheaties, boys across the nation would, too. Early popularity led to commissioning of a radio serial broadcast.

Only the adventures were a product of Gale's imagination. There was a real Jack Armstrong, a member of Sam Gale's college fraternity, Phi Sigma Kappa at the University of Minnesota. Gale met Jack while serving as a young advisor to the fraternity, and being impressed by both the red-blooded name and the "wholesome nature" of the young man, he incorporated it as the name of his new invented spokesman. The adventures which captivated listeners each week were entirely fictitious, and led to good-natured ribbing throughout Armstrong's life. Another creation of Sam Gale's fertile mind was the iconic Betty Crocker.

The radio serial maintained its popularity from 1933 to 1951. The storylines centered on the globe-trotting adventures of Armstrong (played by Jim Ameche until 1938 and later portrayed by Michael Rye), 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 from 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)
