What forms did american propaganda take during wwii? what was its purpose? what were some of the common messages and themes seen in american propaganda?

In 1942, President Franklin D. Roosevelt created the Office of War Information (OWI). This mid-level agency joined a host of other wartime agencies, including the War and State Departments, in the dissemination of war information and propaganda. Officials at OWI used numerous tools to communicate to the American public. These included Hollywood movie studios, radio stations and printing presses. The Writers' War Board was privately organized for the purposes of propaganda and often acted as liaison between the government and the writers. Many of the writers involved regarded their efforts as superior to governmental propaganda, as they regarded their material as bolder and more responsive than governmental efforts. However, the writers both responded to official requests and initiated their own campaigns. In 1944 (lasting until 1948), prominent U.S. policy makers launched a domestic propaganda campaign aimed at convincing the U.S. public to accept a harsh peace for the German people. One method used in this campaign was an attempt to remove the commonly held view that the German people and the Nazi party were separate entities. A key participant in this campaign was the Writers' War Board, which was closely associated with the Roosevelt administration.
