Take-Two bought the rights to the Civilization franchise from Infogrames in 2004 for $22.3 million.
In October 2005, 2K Games, a Take-Two subsidiary, published Civilization IV, which was developed by Firaxis and had Soren Johnson as game designer.
Take Two bought Firaxis for $26.7 million including possible performance bonuses in November 2005. So as of 2008, Take Two owns both the developer and the publisher of the Civilization franchise.
