Comic Books as American War Propaganda

In World War II and the Cold War, government agencies recognized how powerful comic books were and exploited the medium to sell the idea of America across the world. Although by 1954, legislators had become alarmed by the violent and sexual content of comics, and stepped in to force the industry to self-regulate. Other parts of the federal government saw potential in the medium's reach and appeal, and exploited it. The Writer's War Board and, later, agencies within the State Department found ways to use comic books to sway hearts and minds across the globe toward the objectives of the American government.
