The committee on Public Information was created by presidenet Woodrow Wilson. The main goal of the operation was to influence U.S. citizens to an opinion in the United States entering World War 1. The committee used posters and ad campaigns in order to persuade the public in enlisting or supporting the war effort.

Although the committee was created by Woodrow Wilson, on April 13, 1917. There


were many others apart of the committee including, George Creel, Robert Lansling, Newton D. Baker, and Josephus Daniels.  George Creel was the chairman of the committee, he encouraged president wilson to not advertise the same way the Germans had, but to propaganda in the true sense of the word. Creel was a journalist with years of experience with various news and writing companies.

The goal of the committee was to have citizens support or enlist in the war. After using newsprints, posters, radios, telegraphs, and movies to inform citizens they gained 75,000 "four Minute Men" these people were volunteers who spoke out to communities about the war. They would present for 4 minutes and then leave the stage. Four minutes because back then that was the average attention span for humans. These volunteers presented 7.5 million speeches to around 314 million people in 5,200 communities.

    Eventually The Committee of public information extended its operations overseas to Europe, where they set up and  did the same thing they had done in the U.S. Later the organization went into Latin America and began operations.

In July 1918 the committee was terminated after the Armistice was signed on November 11, 1918. Foreign operation were then taken down later in 1919.
