Meaning of Propaganda

According to Garth S. Jowett and Victoria O'Donnell:

"A communication approach to the study of propaganda enables us to isolate its communicative variables, to determine the relationship of message to context, to examine intentionality, to examine the responses and responsibilities of the audience, and to trace the development of propagandistic communication as a process."

While propaganda and persuasion often get intertwined, propaganda has its own meaning. It differs from persuasion because propaganda is about deliberate promoting of ideas, while persuasion is more about convincing the audience of an idea. Propaganda is studied in several different courses of study, but stands out mostly in the area of journalism.
