NDS

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. The DS was among the first portable consoles to support wireless connectivity for local multiplayer over short distances, as well as online play through the now-defunct Nintendo Wi-Fi Connection service. Its primary competitor during the seventh generation of video game consoles was Sony's PlayStation Portable.
