Recognized as the undisputed industry leader, Sony Computer Entertainment America LLC markets the PlayStation family of products and develops, publishes, markets and distributes software for the PS one, PlayStation 2, PSP, PSPgo, PS3, PS4 and PS Vita systems for the North American market.
In the games division, Sony had a decrease in sales for the PS3, PSP and PS Vita of 12.2 percent from last year, although of course it's counting on the PS4 to turn that around.
The PSP and the PS Vita also never officially made it to China presumably due to the strict content restrictions, but like many other flagship gadgets, they were quite popular on the black market.
