The first known Kirk/Spock fan fiction story was "A Fragment Out of Time" by Diane Marchant, published in the fanzine "Grup" #3 (September 1974). It consisted of a sex scene but was written to not identify its participants nor make both of their sexes clear; Marchant stated in the next issue, however, that they were Kirk and Spock. Although many early "Star Trek" fans were fans of science fiction in general, as the show's popularity increased, it acquired fans who were not general science fiction fans but rather found the show appealed to them as a "buddy" show, or as a heroic/romantic saga, in which Kirk and Spock were the focus. This led to a quantity of fan fiction about the show focusing on the relationships between characters on the show, with less of an emphasis on science-fictional elements. Many of these fans found that Kirk and Spock's deep friendship was the most interesting topic for writing about "Star Trek" fan fiction.
