How many seasons did the original Star Trek TV show run?

Who could forget the outer-space adventures of Captain James T. Kirk and his trusted sidekicks Spock and Dr. Leonard H aboard the starship Enterprise. The original show aired on NBC from September 8, 1966, to June 3, 1969. Star Trek is one of the shows that had a big role in popularizing the science-fiction genre on-screen.

Despite the iconic nature of the original show now, after having kicked off an entire franchise of numerous movies and TV shows, it was not that popular when it aired in the 1960s. In fact, the show was canceled on NBC due to low ratings.

The show is often praised for its scientific accuracy, even by today’s standards. Even NASA wrote about how scientifically accurate the show was.
