The Nintendo DS is a handheld game console developed and manufactured by Nintendo. It was released in 2004 in Canada, U.S., and Japan. The console features a clamshell design, similar to the Game Boy Advance SP, with two LCD screens inside - with the bottom one being a touchscreen. The Nintendo DS also features a built-in microphone and supports wireless IEEE 802.11 (Wi-Fi) standards, allowing players to interact with each other within short range (10–30 m, depending on conditions) or online with the Nintendo Wi-Fi Connection service, which launched later in the console's lifespan.
