"Science fiction is a genre of popular culture, commonly considered to have emerged as a literature in the West in the nineteenth century, which addresses what it means to live in technologically saturated societies. Since its consolidation in mass cultural pulp magazines and novels in the 1920's, the genre has burst the bounds of the printed word and developed distinct forms in comic strips, radio, cinema, television, and computer games."
