“People who are fans of a fiction genre, or of a subgenre, who have their own clubs, conventions and amateur magazines (fanzines), dating back (in some cases) to the early 1930s. Some of these are overlapping. Star Trek fandom, for example, started in science fiction fandom and eventually became a separate fandom on its own.”* Fandom is people who have created a cult like following of a Television programme, Film, book or comic. The most well known of these are “Trekkies”**, or fans of Star Trek. Fans also create their own works that are based on that which they are fans of. This can include fan-fiction (Fan made stories), fan made films and trailers as well as fan made websodies (These are episode made for the internet). Some television shows have started through the use of websodies i.e. Sanctuary.
