Wilson established the first modern propaganda office, the Committee on Public Information (CPI), headed by George Creel. Creel set out to systematically reach every person in the United States multiple times with patriotic information about how the individual could contribute to the war effort. It also worked with the post office to censor seditious counter-propaganda. Creel set up divisions in his new agency to produce and distribute innumerable copies of pamphlets, newspaper releases, magazine advertisements, films, school campaigns, and the speeches of the Four Minute Men. CPI created colorful posters that appeared in every store window, catching the attention of the passersby for a few seconds. Movie theaters were widely attended, and the CPI trained thousands of volunteer speakers to make patriotic appeals during the four-minute breaks needed to change reels. They also spoke at churches, lodges, fraternal organizations, labor unions, and even logging camps.
