Office of War Information

Overview
During the Second World War, President Franklin Roosevelt established the Office of War Information (OWI) to provide American and foreign audiences with news of the war, U.S. war policies, and the activities and aims of the U.S. government. Voice of America (VOA), which is the oldest of the U.S. government radio broadcasting services was an integral part of OWI's programs. In 1948, President Harry Truman issued Executive Order 9608, terminating the OWI and transferring its international information functions to the Department of State.
