The Oxford English Dictionary Online, defines a work of satire as that “… which uses humour, irony, exaggeration, or ridicule to expose and criticize prevailing immorality or foolishness, especially as a form of social or political commentary.”
You may already be familiar with popular satirical news sites like the Borowitz Report, the Onion, or SatireWire.
But there are many, many more. Some satirical news sites are easy to identify simply from their titles, with names such as Click Hole, the Daily WTF, and the Oxymoron.
However, others have names that seem as if they could be reputable, like the Daily Currant, the Valley News, and Weekly World News. It may be easy to tell on the satirical newspaper website that it is not reporting real news, but if you read one article in isolation, it can be more difficult.
These sites can help you determine if you're looking at a satirical source. As with any fact-checking site, use these resources judiciously.
