Nintendo DS

The Nintendo DS[b]  or simply DS, is a dual-screen handheld game console developed and released by Nintendo. The device released globally across 2004 and 2005. The DS, an acronym for "Developers' System" or "Dual Screen",[4]  introduced distinctive new features to handheld gaming: two LCD screens working in tandem (the bottom one being a touchscreen), a built-in microphone and support for wireless connectivity.[5]  Both screens are encompassed within a clamshell design similar to the Game Boy Advance SP. The Nintendo DS also features the ability for multiple DS consoles to directly interact with each other over Wi-Fi within a short range without the need to connect to an existing wireless network. Alternatively, they could interact online using the now-defunct Nintendo Wi-Fi Connection service. Its main competitor was Sony's PlayStation Portable during the seventh generation of video game consoles.
