Since the characteristic elements of science fiction can occur in any setting, science fiction lends itself to combination with other genres. In 1953, J. B. Priestley described the "Western" as one of the three types of science fiction. The film serial The Phantom Empire has been cited as possibly the earliest science fiction Western primarily because it takes place on a dude ranch (with many of the props associated with conventional 19th century westerns) while showcasing technology not in existence during that period. Since then, science fiction Westerns have appeared in film, television, novels, comic books, and other media. The 2002 television series Firefly was described as a science fiction Western, since it combined the visual elements associated with Westerns (revolvers, horses, etc.) with those associated with science fiction; however, creator Joss Whedon said that the term made people "cringe".Deep Range by Arthur C. Clarke is considered another example.
