Following the success of Grand Theft Auto: Vice City, consumers anticipated a new Grand Theft Auto game to follow. The first concrete evidence of a new installment came on October 29, 2003, when Take-Two Interactive announced that an untitled GTA game was set for release in the "later half of the fiscal fourth quarter 2004". Although no further information was available at that point, as to the setting or plot of the new game, there were rumors that it would be based in either the fictional city of San Andreas, California or a Las Vegas-themed Sin City, Nevada. On March 1, 2004, Take-Two announced in a press conference that Grand Theft Auto: San Andreas would be released on October 19, 2004 in North America, October 22 in Europe, and October 29 for Australia. The first news of the game's content was revealed on March 11, when it was divulged that San Andreas would not be a city, but rather an entire state consisting of three whole cities and the surrounding territory.
On September 9, 2004, in Take-Two's third quarter financial results for 2004, it was announced that the release date would be pushed back by a week. In the same release, Take-Two announced the Microsoft Windows and Xbox versions of the game.
San Andreas was released for the PlayStation 2 on October 26, 2004 in North America and on October 29, 2004 in Europe and Australia. It was released in Japan on January 25, 2007. The Windows and Xbox ports were released on June 7, 2005 in North America and June 10, 2005 in Europe and Australia.
On October 20, 2008 it was made available to download from the Xbox Live Marketplace as an Xbox Original at the cost of 1200 Microsoft points.
