In December, 2006, Travelport, owner of the Galileo GDS, Gullivers Travel Associates (GTA) and a controlling share in Orbitz, agreed to acquire Worldspan. However, at the time, management of Travelport did not commit to the eventual merging of the two GDS systems, saying that they were considering all options, including running both systems in parallel.[2] On August 21, 2007, the acquisition was completed for $1.4 billion and Worldspan became a part of Travelport GDS, which also includes Galileo and other related businesses. On September 28, 2008, the Galileo and Apollo GDS were moved from the Travelport datacenter in Denver, Colorado to the Worldspan datacenter in Atlanta, Georgia (although they continue to be run as separate systems from the Worldspan GDS).
