Today propaganda, like a gun, is a common weapon of war. It was not until World War I, however, that U.S. Government developed its first massive propaganda campaign.
President Woodrow Wilson created a Committee on Public Information. This committee mobilized citizen support for the war through patriotic speeches, poster campaigns, newspaper stories, films, and pamphlets. Abroad, the committee operated a worldwide information service, distributed films, and with the help of the U.S. Army directed propaganda materials at the enemy.
