Propaganda: Slanted, biased, prejudiced or partial presentation of something that is meant to produce a state of belief that is not proportional to the evidence.
Most points of view people get exposed to are kinds of propaganda, whether political, religious or economical. And indeed, the last kind of propaganda, also known as advertising, is the most expensive and well-paid kind of writing or filming there is, and the sort of information most people are most exposed to.
Advertisement and public relations are also kinds of propaganda, intended to mislead a public into buying products or believing institutions, political parties or governments. Of course, the commercial spreaders or lies that are public relations companies deny this, but then their craft is the art of lying, using the techniques of conmanship.
