Hollywood is a brutal industry, and sometimes even the highest-quality shows are subject to unceremonious cancelation.

But even if your favorite niche show (that's definitely the best thing on TV so how come nobody else watches it?) does get nuked, try not to lose hope. If enough people are as passionate about it as you are, band together and combine your powers. Persistence pays off, and if you're loud enough, you just might manage to save your favorite show. After all, there's a lot of precedence for fans saving TV shows.

Star Trek: The Original Series

  

NBC

Star Trek: The Original Series, considered by many to be amongst the greatest pieces of science fiction ever created, was rumored to be on NBC's chopping block after its second season. This resulted in a massive fan letter-writing campaign, wholly unprecedented for the 1960s. NBC received anywhere from 116,000 to over a million letters over the course of just a few months, so of course they gave Star Trek: The Original Series a third season.
