Star Trek is an American science fiction entertainment franchise based on the television series created by Gene Roddenberry. The first television series, simply called Star Trek and now referred to as The Original Series, debuted in 1966 and aired for three seasons on the television network NBC. It followed the interstellar adventures of Captain James T. Kirk (William Shatner) and his crew aboard the starship USS Enterprise, a space exploration vessel, built by the interstellar federal republic United Federation of Planets in the twenty-third century. The Star Trek canon of the franchise include The Original Series, an animated series, four television series, its film franchise and an upcoming television series scheduled to debut in 2017.

In creating Star Trek, Roddenberry was inspired by the Horatio Hornblower novels, the satirical book Gulliver’s Travels, and by works of western genre such as the television series Wagon Train. These adventures continued in the short-lived Star Trek: The Animated Series and six feature films. Four spin-off television series were eventually produced: Star Trek: The Next Generation followed the crew of a new starship Enterprise set a century after the original series; Star Trek: Deep Space Nine and Star Trek: Voyager set contemporaneously with The Next Generation; and Star Trek: Enterprise set before the original series in the early days of human interstellar travel. Four additional The Next Generation feature films were produced. In 2009, the film franchise underwent a “reboot” set in an alternate timeline, or “Kelvin Timeline”, titled simply Star Trek. This film featured a new cast portraying younger versions of the crew from the original show; their adventures were continued in the sequel film, Star Trek Into Darkness (2013). The thirteenth film feature and sequel, Star Trek Beyond (2016), was released to coincide with the franchise’s 50th anniversary. A new Star Trek TV series, titled Star Trek: Discovery, will premiere in May 2017 on the digital platform CBS All Access.
