"The history of the Star Trek personal computer game franchise began as early as 1971, with a Star Trek text-only computer game written in BASIC. Many PC titles have since been published, and the franchise was one of the first based on a TV program to break into the young PC gamer market in the 1990s.
Interplay, Simon and Schuster, Microprose and Activision released most of the best-known Star Trek games between 2000 and 2003. Titles like Star Trek: Armada, Star Trek: Elite Force and Star Trek: Bridge Commander were all published during this period, as were over half of all the other major Star Trek PC games. The absence of new titles after 2003 was due in large measure to a split and subsequent lawsuit between Activision and Viacom which ended in 2004.
With the departure of Activision in 2003, the franchise under the tenure of Paramount effectively came to a close. Since the end of 2005, CBS has assumed most franchise management, including games and other products. Even with no new licensed titles released during 2003-2006, the older games like Armada and Elite Force still have an avid fan base which keeps the small community going. Development of the new Star Trek: Online title is complete and the game was made available for sale on February 2, 2010."
