The writers of Cavalcade of America supported this move by DuPont, as the staff was made up of mainly young academics that were either pacifists or signed an anti-war pledge in college. With new writers and a world-class PR firm, DuPont was able to shake the “merchant of death” label and remained a sponsor for a top radio program. Cavalcade of America was an early exercise in corporate image-building. DuPont promoted itself as a hero for America. This type of propaganda was shrewd but effective; it put a corporate image behind the real-life heroes that lived a century before.
