Space, the Final Frontier. These are the voyages of the Starship Enterprise. It's five year mission; to explore strange worlds, to seek out new life and new civilizations, to boldly go where no man has gone before! These are the original television adventures of Captain Kirk, Science Officer Spock, and Doctor McCoy.

Star Trek was an American produced sci fi TV series starring William Shatner, Leonard Nimoy, and DeForest Kelley. Created by Gene Roddenberry, Star Trek was originally not very popular at all when it was on the air despite winning two Hugo Awards. It was ultimately cancelled after three seasons due to its lackluster ratings.

However, it gained a massive resurgence in popularity due to reruns and quickly became a part of pop culture and a cult phenomenon. It created a hugely popular and immensely successful and hugely influential Star Trek Franchise that has lasted for decades.  Star Trek has been spoofed and lampooned by various other series including The Muppet Show; Saturday Night Live; and In Living Color over the ensuing decades as well.

There has been a cartoon sequel series, Star Trek: The Animated Series and six movies directly based on the original series and characters. A seventh film, Star Trek: Generations served as a bridge between the original series and the sequel film series that focuses on a future crew approximately 100 years following the events of the original series. 

At present, there have been five official TV spin-off series and a number of fan-based non-profit films and web series have also been created and released. 

For this reason, Star Trek is retroactively referred to as Star Trek: The Original Series or Star Trek: TOS to differentiate between the original television series and the numerous other series and films that was inspired by it. The original series was subsequently digitally remastered with new updated and upgraded special effects and scenes in 2009.

Due to the commercial and critical failures of the last few Star Trek films and television series, the decision was made to reboot the entire franchise. The result was a new feature film in 2009, Star Trek which is based upon the original series which followed up with two sequels films which have ensured that the voyages of Kirk, Spock, and Dr. McCoy will continue.
