"Command & Conquer (often abbreviated as C&C or CnC) is a video game franchise, mostly of the real-time strategy style as well as a first-person shooter game based on the former. The Command & Conquer series was initially developed by Westwood Studios between 1995 and 2003, with development being taken over by Electronic Arts with the liquidation of Westwood Studios in 2003.
The first installment of the series was released worldwide on August 31, 1995 and was simply named Command & Conquer. It was based on Westwood Studios' earlier strategy game Dune 2. The series was originally marketed to an Anglophone audience, though many of the games have been translated into other languages including German, French, Spanish, Korean and Chinese. The series is primarily developed for personal computers running Microsoft Windows, although some titles have been ported to various video game consoles and the Apple Macintosh. The later games of the series starting with Tiberium Wars have also been developed in parallel for Xbox 360. Another spin-off game, Command & Conquer: Red Alert 3, was developed for PC/Mac, Xbox 360, and PlayStation 3.
In 1999, American game marketer and developer Electronic Arts purchased Westwood Studios. Westwood was eventually closed down in 2003 and absorbed into EA Los Angeles which has become the current development center for the ongoing Command and Conquer series. Some of the original Westwood developer team remained at EA Los Angeles, but most left to form Petroglyph Games.
As of July 2009, the Command & Conquer franchise consists of eight games and ten expansion packs with sales of more than 30 million units worldwide."
