The cancellation of Enterprise ended an 18-year run

Star Trek: Enterprise, originally titled Enterprise, is a prequel to the original Star Trek series. It aired from September 26, 2001 to May 13, 2005.[49] Enterprise takes place in the 2150s, some 90 years after the events of Zefram Cochrane's first warp flight and about a decade before the founding of the Federation. The show centers on the voyages of Earth's first warp-five capable starship, the Enterprise, commanded by Captain Jonathan Archer (played by Scott Bakula), and the Vulcan Sub-Commander T'Pol (played by Jolene Blalock).

During the show's first two seasons, Enterprise featured self-contained episodes, like The Original Series, The Next Generation and Voyager. The third season consisted of one arc, "Xindi mission", which had the darker tone and serialized nature of Deep Space 9. Season 4 consisted of several two to three episode mini-arcs. The final season showed the origins of elements seen in earlier series, and it rectified and resolved some core continuity problems between the various Star Trek series. Ratings for Enterprise started strong but declined rapidly. Although critics received the fourth season very well, both fans and the cast reviled the series finale, partly because of the episode's focus on the guest appearance of members of The Next Generation cast.[50] The cancellation of Enterprise ended an 18-year run of back-to-back new Star Trek shows beginning with The Next Generation in 1987.
Paramount Pictures has produced twelve Star Trek feature films, the most recent being released in May 2013.[51] The first six films continue the adventures of the cast of The Original Series; the seventh film, Generations was designed as a transition from that cast to The Next Generation television series; the next three films, 8–10, focused completely on the Next Generation cast.[Note 7] The eleventh and twelfth films take place in an alternate timeline from rest of the franchise set with a new cast playing the original series characters, and with Leonard Nimoy as an elderly Spock providing a physical link to the original timeline.
