The PSP is Japan's 4th highest selling video game platform of all time. In Europe, it performed as you'd have expected, 8th highest selling video game platform in Europe. And in the rest of the world, it's the 2nd highest selling video game platform of all time.
In North America however, it sold poorly in comparison. It's the 12th highest selling video game platform in North America, behind the SNES and Atari 2600.
So why did it sell poorly in North America? The PSP would have easily been the 6th highest selling (until the PS3 surpassed it's sales) video game platform worldwide. Instead it's 9th with a very slight chance of taking 8th.
