Re: Debate/Dislike a Ship Thread -- CSI:Crime Scene Investigation, Par Here's what Wikipedia says about canon: A canon, in terms of a fictional universe, is a body of material that is considered to be "genuine" or "official". The use of the word "canon" in reference to a set of texts derives from Biblical canon, the set of books which are regarded as scripture. The term was first used in the context of fiction to refer to the Sherlock Holmes stories and novels written by Sir Arthur Conan Doyle, to distinguish those works from subsequent pastiches by other authors. It has subsequently been applied to many media franchises, in particular science fiction franchises such as Star Trek and Star Wars, in which many stories have been told in different media, some of which contradict or appear to contradict each other. Hope ^^that^^ helps on what "canon" means.
