The Nebula Award for Best Script was given each year by the Science Fiction and Fantasy Writers Association (SFWA) for science fiction or fantasy scripts for movies or television episodes. Awards are also given out for published literary works in the novel, novella, novelette, and short story categories. The Nebula Award for Best Script was awarded annually from 1974 through 1978, and from 2000 through 2009. It was presented under several names; in 1974, 1975, and 1977 the award was for Best Dramatic Presentation, while in 1976 the award was for Best Dramatic Writing. The award was discontinued in 2010 and replaced with The Ray Bradbury Award for Outstanding Dramatic Presentation; this award, though not a Nebula, is presented at the Nebula Awards Ceremony and follows Nebula rules and procedures. The Nebula Awards have been described as one of "the most important of the American science fiction awards" and "the science-fiction and fantasy equivalent" of the Emmy Awards. Source: Wikipedia (en)
