The PlayStation 2 was released back in Oct. 2000. That's well over a decade ago, and the damn thing is still selling—and selling lots.
As Kotaku marveled back in Feb. 2011, the PS2 continues to shift consoles. And today, Kotaku will marvel at this some more.
According to an official Sony Computer Entertainment release, "The PlayStation 2 platform continues its sales momentum and remains robust sales especially in emerging counties and regions such as Eastern Europe, the Middle East, Southeast Asia and South America, and exceeded half million units worldwide."
That's not only nuts, that means the PS2, a decade-old console sold as well as the brand new PS Vita.
No doubt the PS2's affordable price tag and extensive game library makes the console very attractive to those folks just getting into gaming. There's a reason Sony has sold over 150 million of these things.
Note: according to Sony, the holiday period is "from November 21, 2011 to January 5, 2012 for Japan and Asia, from November 21 to December 31, 2011 for North America, and from November 18 to December 31, 2011 for Europe / PAL territories."
