ABSTRACT
The campaign of the Committee on Public Information (CPI) was an ambitious attempt by the U.S. government to influence public opinion. More importantly, the CPI contributed to the evolution of public relations through its use of basic principles of effective communication including unity of voice, message simplicity, and source credibility. The committee’s campaign encouraged citizens to be stakeholders in their government and heightened their sense of community. The work of the CPI followed a period of unrest between industrialists and journalists and was an important link between the recognition of the need for public relations services and an understanding of the means through which public opinion is crystallized.
