The 3DS, the first widely used 3D video game console has managed to beat the 5 million selling record of other famous consoles, including the well known Wii and older beloved ones like the Game Boy Advance in Japan. The 3DS managed to cross the 5 million mark for Japanese sales in 52 weeks, while it took 58 weeks for the Game Boy Advance and 56 weeks for the DS. The statistics given were based on the number of consoles sold from retailers to buyers so the numbers of other means of purchasing a 3DS were not taken into account.
