Compared to its predecessor, the PS2 is selling in an accelerated pace. The 90-million mark was reached 27 months quicker. A major contributor to the success was the introduction of the slim-line PS2 in November of last year, Sony said.
Global shipments of PlayStation 2 included 36.5 million units in North America, 32.5 million in Europe and 21.0 million in Asia, according to the company.
Sony has said that, even with the PS3 shipping in 2006, it will be continuing to release software titles for the PS2 - a smart move given these figures.
