grey propaganda การใช้

Opposition to grey propaganda, when revealed ( often by an inside source ), may create some level of public outcry.
Radio Free Europe and Radio Liberty, which were, in part, supported by the Central Intelligence Agency, provided grey propaganda in news and entertainment programs to Eastern Europe and the Soviet Union respectively.
Black propaganda contrasts with grey propaganda, the source of which is not identified, and white propaganda, in which the real source is declared and usually more accurate information is given, albeit slanted, distorted and omissive.
This is most commonly to disguise the true origins of the propaganda, be it from an enemy country or from an organization with a negative public image . "'Grey propaganda "'is propaganda without any identifiable source or author.
