Sony recently revealed that 9.7 million PlayStation 4 games were sold online and in retail stores by the end of 2013. The electronic entertainment brand also saw 4.2 million PS4s fly off the shelves worldwide between Nov. 15 and Dec. 28.

Titles were purchased at stores and web sites like GameStop, Wal-mart, Amazon and Target. They were also bought digitally over the PlayStation Network. “Call of Duty: Ghosts,” “Assassin’s Creed IV: Black Flag,” “Battlefield 4,” “FIFA 14” and “Killzone: Shadow Fall” were among the best-selling games on the console.

Sony also stated that PlayStation Plus subscriptions have increased more than 90 percent since the PS4 launched in November, and officials “couldn’t be more thrilled” with the success of the next-gen system.

Currently, international demand for the PlayStation 4 seems to be outpacing Microsoft’s Xbox One, which launched in 13 countries on Nov. 22. Though Microsoft is selling well in the U.S. market, global buyers seem to prefer Sony’s latest endeavor. Both systems found immediate success, with the Xbox One and PS4 selling 1 million units within 24 hours after their official releases in November. Sony called the PS4 launch its most successful console release of all time, and Sony President and Group CEO Andrew House thanked Sony fans at 2014 International CES last week in Las Vegas.

"The momentum of the PS4 system keeps getting stronger and we couldn't be more thrilled gamers worldwide are enjoying the incredibly immersive gaming experiences along with deep social capabilities and entertainment provided by our network," House said at the annual consumer electronic's show. "After a remarkable launch, we look forward to bringing even more exciting content and continuing to explore the power of the PS4 system by adding new features and services, including PlayStation Now, in 2014."
