Propaganda is "information, especially of a biased or misleading nature, used to promote a political cause or point of view". Propaganda is often associated with the psychological mechanisms of influencing and altering the attitude of a population toward a specific cause, position or political agenda in an effort to form a consensus to a standard set of belief patterns.
Propaganda is information that is not objective and is used primarily to influence an audience and further an agenda, often by presenting facts selectively (perhaps lying by omission) to encourage a particular synthesis or perception, or using loaded messages or "loaded language" to produce an emotional rather than a rational response to the information that is presented. Propaganda is often associated with material prepared by governments, but activist groups and companies can also produce propaganda.
In the twentieth century, the term propaganda has been associated with a manipulative approach, but propaganda historically was a neutral descriptive term. A wide range of materials and media are used for conveying propaganda messages, which changed as new technologies were invented, including paintings, cartoons, posters, pamphlets, films, radio shows, TV shows, and websites.
Propaganda is a modern Latin word, the gerundive form of propagare, meaning to spread or to propagate, thus propaganda means that which is to be propagated. Originally this word derived from a new administrative body of the Catholic church (congregation) created in 1622, called the Congregatio de Propaganda Fide (Congregation for Propagating the Faith), or informally simply Propaganda. Its activity was aimed at "propagating" the Catholic faith in non-Catholic countries.
From the 1790s, the term began being used also to refer to propaganda in secular activities. The term began taking a pejorative or negative connotation in the mid-19th century, when it was used in the political sphere.
