Throughout history, mankind has attempted to influence others for a variety of reasons and they developed techniques to improve the chances of affecting behaviors. The collection of these techniques is called propaganda. From it's early beginnings as a way to spread the Christian religion, to modern techniques developed to mass market consumer goods, propaganda has been honed and shaped to allow the public to be influenced on a variety of different levels and usually without their knowledge or consent. While these techniques can be used to sell goods or rally a populace around a war, they can also be used to change corporate culture.
