Propaganda in the United States

Propaganda in the United States is spread by both government and media entities. Propaganda is information, ideas, or rumors deliberately spread widely to influence opinions, usually to preserve the self-interest of a nation. It is used in advertising, radio, newspaper, posters, books, television and other media and may provide either factual or non-factual information to its audiences.
Domestic.
World War I.
The first large-scale use of propaganda by the U.S. government came during World War I. The government enlisted the help of citizens and children to help promote war bonds and stamps to help stimulate the economy. To keep the prices of war supplies down (guns, gunpowder, cannons, steel, etc.), the U.S. government produced posters that encouraged people to reduce waste and grow their own vegetables in "victory gardens". The public skepticism that was generated by the heavy-handed tactics of the Committee on Public Information would lead the postwar government to officially abandon the use of propaganda.
The 1915 film "The German Side of the War" compiled from footage filmed by "Chicago Tribune" cameraman Edwin F. Weigle. It was one of the only American films to show the German perspective of the war. At the theater lines stretched around the block; the screenings were received with such enthusiasm that would-be moviegoers resorted to purchasing tickets from scalpers.
World War II.
During World War II, the United States officially had no propaganda, but the Roosevelt government used means to circumvent this official line. One such propaganda tool was the publicly owned but government-funded Writers' War Board (WWB). The activities of the WWB were so extensive that it has been called the "greatest propaganda machine in history". "Why We Fight" is a famous series of US government propaganda films made to justify US involvement in World War II. Response to the use of propaganda in the United States was mixed, as attempts by the government to release propaganda during World War I was perceived negatively by the American public.
