What TV show did/do you wish wasn't cancelled or put out to pasture too soon?

41. Yep. And NBC reportedly did everything they could to kill it.

Season 3 (1968–1969)

NBC at first planned to move Star Trek to Mondays for the show's third season, likely in hopes of increasing its audience after the enormous letter campaign that surprised the network. In March 1968; however, NBC instead moved the show to 10:00 pm Friday night, an hour undesirable for its younger audience, so as not to conflict with the highly successful Rowan & Martin's Laugh-In on Monday evenings, from whose time slot Laugh-In producer George Schlatter had angrily demanded it not be rescheduled. In addition to the undesirable time slot, Star Trek was now being seen on only 181 of NBC's 210 affiliates.

Roddenberry was frustrated, and complained, "If the network wants to kill us, it couldn't make a better move." He attempted to persuade NBC to give Star Trek a better day and hour, but was not successful. As a result of this and his own growing exhaustion, he chose to withdraw from the stress of the daily production of Star Trek, though he remained nominally in charge as its "executive producer".

Roddenberry reduced his direct involvement in Star Trek before the start of the 1968–69 television season, and was replaced by Fred Freiberger as the producer of the television series. Arthur H. Singer served as story editor. NBC next reduced Star Trek's budget from $185,000 per episode in season 2 (it was $190,000 per episode in season 1) to $175,000 per episode in season 3 (as the per-minute commercial price had dropped from $39,000 to $36,000 compared to the season-two time slot). This caused what some perceive as a decline in quality for the 1968–69 season, although there was a trade off in some lower production costs since the special effects technology had improved over time.

By season 3 William Shatner felt that the main characters had become more compromised or exaggerated and the story lines more improbable. Leonard Nimoy felt that financial concerns dominated. Associate Producer Bob Justman, who left during the third season, said budget cuts caused the crew to become necessarily limited in the type of filming that could be done, such as outdoor work, with only one episode, "The Paradise Syndrome", shot largely outdoors. Nichelle Nichols described the budget-cutting during the final year as an intentional effort to kill off Star Trek:

While NBC paid lip service to expanding Star Trek's audience, it [now] slashed our production budget until it was actually 10% lower than it had been in our first season ... This is why in the third season you saw fewer outdoor location shots, for example. Top writers, top guest stars, top anything you needed was harder to come by. Thus, Star Trek's demise became a self-fulfilling prophecy. And I can assure you, that is exactly as it was meant to be.

The last day of filming for Star Trek was January 9, 1969, and after 79 episodes NBC canceled the show in February despite fans' attempt at another letter-writing campaign. One newspaper columnist advised a protesting viewer:

You Star Trek fans have fought the "good fight", but the show has been cancelled and there's nothing to be done now.

In 2011, the decision to cancel Star Trek by NBC was ranked number four on the TV Guide Network special, 25 Biggest TV Blunders 2.
