The history of the Star Trek fandom has been largely defined by its instances of fan mobilization. While the fandom can be said to have come into existence in 1966 with the premier of the first episode of Star Trek, the fandom arguably only truly came into its own when the series was cancelled. As previously discussed, when the original Star Trek series was cancelled in 1968, fans of the series mobilized around a letter writing campaign and “pressure[d] NBC to keep and later return their show to the airways” (Jenkins, as cited by Scardaville, 2005, p.882). Although the show‟s revival lasted only one season, the event marked a turning point for both the Star Trek fandom and for fandoms in general: the success of the letter writing campaign showed that fans can and do have an influence over the decisions producers make – that the power relations between fans and producers are not entirely unilateral. If not the first instance, the letter writing campaign has certainly been the most well documented instance of successful fan mobilization in the history of modern fandoms, and has been the standard for many subsequent fan mobilizations.
