Edward Bernays is best known in mass media circles as the "Father of Propaganda." Scientific techniques were developed and used to shape the psychological decisions and opinions of the masses. 
For example, he was an important part of the U.S. Committee on Public Information (CPI) during World War I, along with Walter Lippmann and Carl Byoir. The propaganda from CPI sold the war to Americans as one that would "Make the World Safe for Democracy."
