Americans through dramatizations, Cavalcade of America caused listeners to associate DuPont's products with patriotism and self-reliance. The series also gave history and chemistry more prestige than it would have otherwise had. By making the show thrilling, but not over-sensationalized, DuPont was able to better its own branding and get away from being perceived as a military-only company. Nylon show On May 15, 1940 DuPont made nylon women's hosiery available to the public and began an advertising blitz. The day was designated "N-day" by DuPont's marketeers, and an entire episode of Cavalcade of America was markedly different: DuPont selected a "typical" housewife to interview G.P. Hoff, Director of Research of DuPont's Nylon Division. In the rigged interview, Hoff expounded at length on the virtues of nylon. Eager to purchase nylon hose, thousands of women waited in lines for department stores to open the following morning. 750,000 nylons had been manufactured for N-Day, but all were sold on the first day they went on sale. Television In the 1950s, DuPont switched its advertising strategy from radio to television, and Cavalcade of America became a television series mainly produced by Jack Chertok. One hundred and thirty-three episodes were aired over five seasons between 1952 and 1957. During a six-month period, the television and radio series overlapped. The show was telecast on both NBC (1952–53) and ABC (1953–57). It was renamed DuPont Cavalcade Theater in August 1955, and it was known as DuPont Theater during its last year. In the 1957 fall season, it was replaced by The DuPont Show of the Month, a 90-minute live dramatization of popular novels and short stories or abridged versions of films and plays. That series ran until 1961. Many kinescopes of Cavalcade of America survive at the UCLA Film and Television Archive. Season 1 (1952–53) Season 2 (1953–54) Season 3 (1954–55) Season 4 (1955–56) Season 5 (1956–57) Books During the late 1930s, Dixon Ryan Fox and Arthur Meier Schlesinger edited a series of books based on the series published by Milton Bradley. In 1956, the series was adapted into a book, Cavalcade of America: The Deeds and Achievements of the Men and Women Who Made Our Country Great, published by Crown. Chapters covered such historical figures as Abraham Lincoln, telegraph organizer Hiram Sibley, engineer James Eads, John Quincy Adams fighting the gag rule and Clara Barton's career that led her to head the American Red Cross.
