The Art Of Propaganda

"To defeat the enemy we must rely primarily on the army with guns. But this army alone is not enough; we must also have a cultural army, which is absolutely indispensable for uniting our own ranks and defeating the enemy."
~Mao Zedong (1942)

A tactic that goes back centuries, if not more.  The Romans liked to assimilate their conquests' cultures to theirs so people wouldn't feel like rebelling.  And the use of TV and cartoons now is still used all over the world for propaganda (or brainwashing)--for "proving" a cause's "justice," or keeping people tame and happy while the government does its dirty business, for example.
