Star Trek is known as one of the most successful science fiction TV shows of all time. The original series, which aired on NBC from 1966-1969 was just the beginning – since then, there have been several spin-off series, as well as 10 movies, not to mention the books, movie merchandise, and immeasurable impact on pop culture. Critics of the series are quick to point out the cheesy special effects and over-the-top acting, but there’s no question that William Shatner became – and continues to be – a household name all because of this series. We take a close look at the elements that had to come together to make Star Trek a multi-season series, and why people can’t seem to get enough of this 60s space drama.
