 Since its launch , monthly sales numbers of the console have generally been higher than its competitors around the globe . According to the NPD Group , the Wii sold more units in the United States than the Xbox 360 and PlayStation 3 combined in the first half of 2007 . This lead is even larger in the Japanese market , where it currently leads in total sales ( having outsold both consoles by factors of 2 : 1 to 6 : 1 nearly every week from its launch to November 2007 ) . In Australia the Wii broke the record set by the Xbox 360 and became the fastest @-@ selling game console in Australian history .
