"Propaganda is neutrally defined as a systematic form of purposeful
persuasion that attempts to influence the emotions, attitudes, opinions, and
actions of specified target audiences for ideological, political or commercial
purposes through the controlled transmission of one-sided messages (which may or
may not be factual) via mass and direct media channels. A propaganda
organization employs propagandists who engage in propagandism—the applied
creation and distribution of such forms of persuasion."
