FRONTLINE takes an in-depth look at the multibillion-dollar "persuasion industries" of advertising and public relations and how marketers have developed new ways of integrating their messages deeper into the fabric of our lives. Through sophisticated market research methods to better understand consumers and by turning to the little-understood techniques of public relations to make sure their messages come from sources we trust, marketers are crafting messages that resonate with an increasingly cynical public. In this documentary essay, correspondent Douglas Rushkoff (correspondent for FRONTLINE's "The Merchants of Cool") also explores how the culture of marketing has come to shape the way Americans understand the world and themselves and how the techniques of the persuasion industries have migrated to politics, shaping the way our leaders formulate policy, influence public opinion, make decisions, and stay in power.
