After Star Trek's second season, NBC was prepared to cancel the show due to low ratings.[45][46] Led by fans Bjo and John Trimble, Trek viewers inundated NBC with letters protesting the show's demise and pleading the network to renew the series for another year.[46][47] After NBC agreed to produce a third season, the network promised Gene Roddenberry that the show would air in a favorable timeslot (Mondays at 7:30 PM),[45][46] but later changed the schedule so that Trek would air in the so-called "death slot" ? Friday nights at 10:00PM.[45][48] In addition to the "mismanaged"[46] schedule, the show's budget was "seriously slashed"[45] and Nichelle Nichols described the series' eventual cancellation as "a self-fulfilling prophecy".[49]

Star Trek's final, 24-episode season began in September 1968 with "Spock's Brain".[2] The third season also includes "The Tholian Web", where Kirk becomes trapped between universes; this episode would later be revisited by two 2005 episodes of the prequel series Star Trek: Enterprise. The last episode of the series, "Turnabout Intruder", aired on June 3, 1969,[2] but Star Trek would eventually return to television in animated form when the animated Star Trek debuted in September 1973.
