"propaganda"

Explanation:

Propaganda is a form of communication that aims to influence the attitude of a community regarding some cause or position, presenting only one side or aspect of an argument. Propaganda is usually repeated and disseminated in a wide variety of media in order to obtain the desired result in the attitude of the audience.

Contrary to the provision of free and impartial information, propaganda, in its most basic sense, presents partial or biased information to influence an audience. It frequently presents facts selectively and deliberately omits others to support a conclusion, or uses controlled messages to produce an emotional, rather than rational, response to the information presented. The desired effect is a change in the attitude of a given audience about political, religious or commercial matters. Propaganda, therefore, can be used as a "weapon of war" in the ideological or commercial struggle.
