The Committee on Public Information (CPI) was created by the US Government on the 13th of April, 1917 to encourage public support for America's involvement in World War I. The committee's purpose was to generate propaganda to promote public backing for the war effort. It did this via magazines, newspapers, movies, posters and, innovatively, by using volunteers known as 'Four Minute Men', who spoke positively about the war for four minutes at social gatherings. It also sought to limit damaging news reports. The CPI was abolished on the 21st August, 1919.
