Actually you can trace it back through the inventor of Propaganda: Ed Bernays
https://en.wikipedia.org/wiki/Edward_BernaysTo the screwball he learned it from, his Uncle, Sigmund Freud
https://en.wikipedia.org/wiki/Sigmund_FreudHitler's propaganda expert was Josef Goebbels. After the war when it was discovered that Goebbells owned all of Bernays books, Bernays changed the name of his snake oil to Building Consensus. He is still the Dean of American Advertising.
Notable clients and campaignsFurther information: Public relations campaigns of Edward Bernays
Bernays's famous corporate clients included Procter & Gamble, the American Tobacco Company, Cartier Inc., Best Foods, CBS, the United Fruit Company, General Electric, Dodge Motors, the fluoridationists of the Public Health Service, Knox-Gelatin, and innumerable other big names.
Bernays attempted to help Venida hair nets company to get women to wear their hair longer so they would use hairnets more. The campaign failed but did get government officials to require hairnets for some jobs.
Bernays worked with Procter & Gamble for Ivory-brand bar soap. The campaign successfully convinced people that Ivory soap was medically superior to other soaps. He also promoted soap through sculpting contests and floating contests because the soap floated better than competing products.
Bernays used his uncle Sigmund Freud's ideas to help convince the public, among other things, that bacon and eggs was the true all-American breakfast.[25]
In the 1930s, his Dixie Cup campaign was designed to convince consumers that only disposable cups were sanitary by linking the imagery of an overflowing cup with subliminal images of vaginas and venereal disease.[26]
He was publicity director for the 1939 New York World's Fair.[27]
Another selection from his papers, the Typescript on Publicizing the Physical Culture Industry, 1927: "Bernarr Macfadden", reveals Bernays' opinion of the leader of the physical culture movement. Yet another client, department store visionary Edward A. Filene, was the subject of the Typescript on a Boston Department Store Magnate. Bernays' Typescript on the Importance of Samuel Strauss: "1924 – Private Life" shows that the public relations counsel and his wife were fans of consumerism critic Samuel Strauss.[citation needed]
