I know it won't happen, but let's say I was the the offical writer for some television series, or something (i.e. I actually created the whole show, as opposed to just writing some of the episodes), but I still use the internet in my free time. Obviously, my TV Series will have some form of fan following online (it's my thread, so I'll say it has a good following, why not? ).

Now, if I was to write a story about my own TV Series that is noncanon from the show's actual storyline, and put it online, would it still be considered fanfiction? just wondering?
