This is a terrific site I stumbled onto a while back:

By way of introduction I selected a book titled "Propaganda" by Edward Bernays published in 1928. The table of contents:

Contents
I. ORGANIZING CHAOS
II. THE NEW PROPAGANDA
III. THE NEW PROPAGANDISTS
IV. THE PSYCHOLOGY OF PUBLIC RELATIONS
V. BUSINESS AND THE PUBLIC
VI. PROPAGANDA AND POLITICAL LEADERSHIP
VII. WOMEN'S ACTIVITIES AND PROPAGANDA
VIII. PROPAGANDA FOR EDUCATION
IX. PROPAGANDA IN SOCIAL SERVICE
X. ART AND SCIENCE
XI. THE MECHANICS OF PROPAGANDA

I was astounded by how sophisticated the understanding of propaganda was in 1928. At that time the application of propaganda to the political sphere was unknown. Propaganda was considered a marketing tool. That was roughly 90 years ago and the utilization of propaganda in politics is universal.

We've come a long way baby! Here's the link to "Propaganda":
