During World War II, the US government waged a constant battle for the hearts and minds of the public. Persuading Americans to support the war effort became a wartime industry, just as important as producing bullets and planes. The Office of War Information (OWI) was formed in 1942 to oversee the propaganda initiative, scripting and distributing the government’s messages. Artists, filmmakers, and intellectuals were recruited to work on this creative “factory floor.” They produced posters, pamphlets, newsreels, radio shows, and movies-all designed to create a public that was 100 percent behind the war effort.

A. National unity
B. Conservation of resources
