“History has shown us that the first company to reach 10 million in console sales wins the generation battle,” Don Mattrick, a Microsoft senior vice president who heads the company’s Xbox business, said in a statement.
The Xbox 360 was the first of this latest generation of game machines to launch in the United States when it was released in November 2005. The PS3 and Wii were launched in the United States a year later.
The Wii is closing in on the Xbox 360, with 8.8 million units sold as of the end of March, while Sony has totaled 4.1 million PS3 units sold, according to market research firm NPD.
Microsoft also said global membership of its Xbox Live online service reached 12 million members.
