Wii

Total units sold:
13.17 million as of September 30, 2007
Since its launch, the monthly sales numbers of the console have been higher than its competitors across the globe. According to the NPD Group, the Wii has sold more units in North America 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 not only in total sales, but usually outsells both consoles by 3:1 to 6:1 every week. In Australia, the Wii exceeded the Xbox 360 to become the fastest selling games console in Australian history. On September 12, 2007, it was reported by the Financial Times that the Wii had surpassed the Xbox 360, which was released one year previously, and had become the market leader in worldwide home console sales for the current generation. This is the first time a Nintendo console has led its generation in sales since the Super Nintendo Entertainment System. Nintendo warned that the Wii would remain in short supply throughout 2007.
While Microsoft and Sony had experienced losses producing their consoles in the hopes of making a long-term profit on software sales, Nintendo claims to have optimized production costs to obtain a significant profit margin with each Wii unit sold. According to the Financial Times, this direct profit per Wii sold may vary from $13 in Japan to $49 in the United States and $79 in Europe.....
