Global cumulative sales of the PlayStation 4 home gaming console topped 10 million units as of Sunday, Sony Corp.'s gaming unit said Wednesday.

Sony, which has been struggling to rebuild its electronics business, is positioning the gaming sector as a pillar for improving its performance.

Since its launch last November, the PS4 gaming system, which features enhanced connectivity with social networks and mobile phones, has become available in 100 countries and regions worldwide, including North America, Europe and Asia.

"I am absolutely delighted that PS4 was able to reach this commemorative milestone in less than nine months," Sony Computer Entertainment Inc. President Andrew House said in a statement. "We look forward to bringing even more exciting content and services in the months ahead."

The PS4 game hardware has been outpacing sales of Microsoft Corp.'s Xbox One, which hit the U.S. and other markets last year.
