Fake News: Politifact/Punditfact recently provided a definition of fake news in their article "Fact-checking fake news reveals how hard it is to kill pervasive ‘nasty weed’ online."
... [Is] a concerted effort by a website or other form of media to fabricate information in order to influence political opinion or win financial gain. Perhaps the most insidious component of these kinds of hoaxes is that quite often, they simply sound plausible, especially to people who want to believe them. That’s because such stories can frequently be based on a kernel of true information, but portray it out of context or surrounded by made-up details.
Propaganda: Propaganda is a communicative technique that seeks to manipulate the opinions and attitudes of a targeted audience. It intends to change existing belief systems, value structures, and political positions in order to create specific attitudes toward a subject of public discourse in a manner favorable to the propagandist. Specific messages usually are linked to an overwhelming ideology. Propaganda is directed at a large number of people and thus is communicated by mass media. It can use different media genres, such as speeches, advertisements, editorials, articles, songs, or posters. Propaganda is a function of the political system and strives to gain or defend political power (Encyclopedia of Political Communication).

Satire: is considered a literary genre; it is often used in the performing arts; and it is used to highlight human folly, vice, abuse, or shortcomings to affect a change in attitude, action, or belief. Thus, satire refers to ridicule or criticism with a moral intention. Commonly, satire is comical although it is not always humorous because the intention is to encourage serious improvement in the lives of the audience. In other words, although satire is often meant to be funny, its purpose is not to merely entertain the audience; the purpose is to specifically condemn the subject by drawing attention to the subject's shortcomings (Encyclopedia of Identity).
