Seven years ago, after the release of the Sony PlayStation 2 and the Microsoft Xbox, it seemed as though Nintendo, once a market leader, would never regain its No. 1 position. The GameCube, which sold a paltry 21.74 million units worldwide, had been a relative dud for the longtime gaming champion. However, undeterred by its third-place position, Nintendo had a plan for the next generation of gaming consoles. Flash forward to 2008: Nintendo has sold some 32.64 million units of the Wii worldwide, according to video game sales tracking firm VG Chartz.
