New Super Mario Bros. Wii is a global sales sensation, having racked up over 16 million sales worldwide since its release just one year ago, with four million of those sales in Japan alone, making it the territory's biggest selling Wii title.

New Super Mario Bros. Wii is the first title to pass the four million milestone in the Land of the Rising Sun, perhaps a surprising statistic considering the machine's been on sale for over four years now, but is proof if any were needed that Mario's popularity lives on.
