I wish people would stop parroting about Goebbels to this phenomena, because the real "innovator" in the propaganda was the nephew of Sigmund Freud, Edward Bernays [1] (Goebbels was a big fan of him). His manipulation techniques and tricks are what started the profession of public relations (PR) in USA.
He also helped spreading the lie that helped CIA overthrow the democratically elected Guatemalan president [2].
Yep, as soon I've found about him, I've checked out the documentary series, it should be viewed in schools. But that would probably be bad for business as it's not OK for masses to be aware of the techniques.
