SF vs. Sci Fi
Science Fiction is defined as a genre/style dealing with extrapolated futuristic science and technology, space travel, aliens, alternate or future settings, and dystopian societies. All of these changes to the settings and environs of the story serve the purpose of commentary on society and human nature.
In 1978, Isaac Asimov published a paper called, The Name of Our Field. Roughly summarized, he explores the origination of the term “science fiction.” At the very end of the article, he touches upon the introduction of the term, sci fi by Forrest J. Ackerman. It is a term mostly used by the entertainment industry, and as Isaac Asimov wrote, “We can define ‘sci-fi’ as trashy material sometimes confused, by ignorant people, with s.f. Thus, Star Trek is s.f. while Godzilla Meets Mothra is sci-fi.”
