Develop the following systems using the propaganda pattern:

1. Atrocity propaganda is a term that refers to the spreading of deliberate fabrications or exaggerations about the crimes committed by an enemy, constituting a form of psychological warfare.
2. A propaganda film is a film that involves some form of propaganda. Propaganda films may be packaged in numerous ways, but are most often documentary-style productions or fictional screenplays, that are produced to convince the viewer of a specific political point or influence the opinions or behavior of the viewer, often by providing subjective content that may be deliberately misleading [8,9].

3. Corporate propaganda refers to propagandist claims made by a corporation (or corporations), for the purpose of manipulating market opinion with regard to that corporation, and its activities. Just as the use of these products and services can provide pluses that outweigh the minuses to society and individuals, their advocacy may function more positively than negatively. Common euphemisms for corporate propaganda are advertising and public relations.
4. Self-propaganda is a form of propaganda and indoctrination performed by an individual or a group on oneself.
