The topic of Star Trek Kirk/Spock slash (homoerotic) fan fiction had been explored in an earlier essay, "Brownian Motion: Women, Tactics, and Technology" (in Technoculture, edited by Penley and Andrew Ross, 1991), and in part of her book, NASA/TREK, but its appearance in the edited volume Cultural Studies drew much positive attention, marked the topic of women writing male-male erotica as falling under the rubric of cultural studies and did much to legitimize and mainstream fan studies.
