How many units did the original Nintendo DS sell worldwide?

The original Nintendo DS family sold 154.02 million units worldwide.

Nintendo introduced the DS in 2004 as a dual-screen handheld. Its lower display was a touch screen, while the upper display showed game action or supplementary information. The system also included a microphone and wireless connectivity, features that broadened the audience beyond conventional button-based games.

The sales total includes the original DS and its major hardware revisions, including the DS Lite, DSi, and DSi XL. Nintendo’s unusually broad software lineup helped the platform reach both established players and newcomers. Games such as Nintendogs and Brain Age were especially important to that expansion.

The DS is often compared with the Game Boy family, but it was a separate product line. Its successor, the Nintendo 3DS, retained the dual-screen concept while adding glasses-free stereoscopic 3D.
