Coming at you from Archive.org is a British documentary on the creation of Public Relations. Here's the blurb from Archive's page: "The history of "Public Relations" also known as manufacturing the public consent, from early days with Edward Bernays to today, from selling cigarettes to women to commercial wars dressed as "war for liberty", political campaing, state-sponsored corporate lies, and world-scale deception since 1920s."
