Science fiction fandom

Science fiction fandom or SF fandom (or Sci-Fi fandom) is a community or fandom of people actively interested in science fiction in contact with one another based upon that interest. SF fandom has a life of its own, but not much in the way of formal organization (although clubs such as the Futurians [1937–1945], the Los Angeles Science Fantasy Society [1934–present], and the National Fantasy Fan Federation [1941–present] are recognized features of fandom).
