Adam Curtis' multi-part documentary on how Freud's ideas and Edward Bernays' public relations shaped consumer culture and political control. It argues that business and government learned to manufacture desires.

The first part of Adam Curtis' documentary series on Sigmund Freud and his nephew Edward Bernays, who invented public relations. It shows how Bernays used Freud's ideas to link mass-produced goods to unconscious desires and create modern consumer persuasion.
