apr 13, 1917 - Committee on Public Information
An independent agency of the government of the United States created to influence public opinion to support US participation in World War I.
In just over 26 months, from April 14, 1917, to June 30, 1919, it used every medium available to create enthusiasm for the war effort and to enlist public support against the foreign and perceived domestic attempts to stop America's participation in the war. It used mainly propaganda to accomplish its goals.
