The Nintendo DS introduced a touchscreen and two separate screens in 2004.
Nintendo released the handheld in North America in November 2004, following its Japanese launch earlier that year. Its two-screen design placed one display above the other, while the lower screen was touch-sensitive and could be used with a stylus. This arrangement created new control possibilities for games and applications.
The DS also supported wireless multiplayer and could play Game Boy Advance cartridges through a dedicated slot. Nintendo marketed it as a third pillar alongside its home consoles and the Game Boy line, although it ultimately became the successor to the Game Boy Advance family in practical terms.
The Nintendo 3DS followed in 2011 and added glasses-free stereoscopic 3D to the upper display. That later handheld is often confused with the original DS, but the DS itself did not provide the same built-in 3D effect.
