Edward Bernays, the US nephew of Sigmund Freud, is said to have invented modern propaganda. During the World War I, he was one of a group of influential liberals who mounted a secret government campaign to persuade reluctant Americans to send an army to the bloodbath in Europe.
In his 1928 book Propaganda, Bernays said the “intelligent manipulation of the organised habits and opinions of the masses was an important element in democratic society” and that the manipulators “constitute an invisible government which is the true ruling power in our country“.
