The Nintendo DS is a foldable handheld game console developed by Nintendo and released worldwide in 2004 and 2005. The "DS" in the name is an initialism for "Dual Screen", reflecting the system's most distinctive feature: two LCD screens working in tandem, with the lower screen functioning as a touchscreen. Both screens are housed in a clamshell design similar to that of the Game Boy Advance SP and some models of the Game & Watch series.
