Yeah, that's why Star Trek was canceled in 1969, nobody was interested in it.
Dumbass.
Actually, everything I've read says that bad ratings are exactly why the original Trek was cancelled.
That's what they say.
Tell me, what replaced Star Trek?
Point made.
Is your point that sometimes shows don't get enough people watching them when they first air, but a following grows later?
What replaced Star Trek has no bearing on whether or not the show was getting good ratings when it was cancelled.
"In 2011, the decision to cancel
Star Trek by NBC was ranked #4 on the
TV Guide Networkspecial,
25 Biggest TV Blunders 2.
["
Hindsight is 20-20. At the time of its cancellation, ST wasn't doing that well.
"
The enthusiasm of
Star Trek's viewers surprised NBC.
[25] The network had already received 29,000 fan letters for the show during its first season, more than for any other except
The Monkees.
[19] When rumors spread in late 1967 that
Star Trek was at risk of cancellation, Roddenberry secretly began and funded an effort by
Bjo Trimble, her husband John and other
fans to persuade tens of thousands of viewers to write letters of support to save the program.
[39][40]:377–394
[41] Using the 4,000 names on a mailing list for a science-fiction convention, the Trimbles asked fans to write to NBC and ask ten others to also do so.
[42]:128 NBC received almost 116,000 letters for the show between December 1967 and March 1968, including more than 52,000 in February alone;
[43][44][19] according to an NBC executive, the network received more than one million pieces of mail but only disclosed the 116,000 figure.
[39] Newspaper columnists encouraged readers to write letters to help save what one called "the best science fiction show on the air".
[45] More than 200
Caltech students marched to NBC's
Burbank, California studio to support
Star Trek in January 1968, carrying signs such as "
Draft Spock" and "
Vulcan Power".
[46] Berkeley and
MIT students organized similar protests in San Francisco and New York.
[45]
The letters supporting
Star Trek, whose authors included
New York State Governor Nelson Rockefeller,
[47] were different in both quantity and quality from most mail that television networks receive:
The show, according to the 6,000 letters it draws a week (more than any other in television), is watched by scientists, museum curators, psychiatrists, doctors, university professors and other highbrows. The
Smithsonian Institution asked for a print of the show for its archives, the only show so honored.
[45]
In addition:
Much of the mail came from doctors, scientists, teachers, and other professional people, and was for the most part literate–and written on good stationery. And if there is anything a network wants almost as much as a high Nielsen ratings it is the prestige of a show that appeals to the upper middle class and high brow audiences.
[35]
NBC—which used such anecdotes in much of its publicity for the show—made the unusual decision to announce on television, after the episode "
The Omega Glory" on March 1, 1968, that the series had been renewed.
[31]:116–117
[47] The announcement implied a request to stop writing,
[39] but instead caused fans to send letters of thanks in similar numbers.
[48]
While NBC paid lip service to expanding Star Trek's audience, it [now] slashed our production budget until it was actually ten percent 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.[56]
