query: When was the DS released?
passage: Nintendo DS
The Nintendo DS,[lower-alpha 2] or simply DS, is a dual-screen handheld game console developed and released by Nintendo. The device went on sale in North America on November 21, 2004. The DS, short for "Developers' System" or "Dual Screen",[4] introduced distinctive new features to handheld gaming: two LCD screens working in tandem (the bottom one featuring 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 as part of the seventh generation era. It was likened to the Nintendo 64 from the 1990s, which led to several N64 ports such as Super Mario 64 DS and Diddy Kong Racing DS, among others.

In 2004, Nintendo released the Nintendo DS, its fourth major handheld system. The DS is a dual screened handheld featuring touch screen capabilities, which respond to either a stylus or the touch of a finger. Former Nintendo president and now chairman Hiroshi Yamauchi was translated by GameScience as explaining, "If we can increase the scope of the industry, we can re-energise the global market and lift Japan out of depression – that is Nintendo's mission." Regarding lukewarm GameCube sales which had yielded the company's first reported operating loss in over 100 years, Yamauchi continued: "The DS represents a critical moment for Nintendo's success over the next two years. If it succeeds, we rise to the heavens, if it fails, we sink into hell." Thanks to games such as Nintendogs and Mario Kart DS, the DS became a success. In 2005, Nintendo released the Game Boy Micro in North America, a redesign of the Game Boy Advance. The last system in the Game Boy line, it was also the smallest Game Boy, and the least successful. In the middle of 2005, Nintendo opened the Nintendo World Store in New York City, which would sell Nintendo games, present a museum of Nintendo history, and host public parties such as for product launches. The store was renovated and renamed as Nintendo New York in 2016.
In the first half of 2006, Nintendo released the Nintendo DS Lite, a version of the original Nintendo DS with lighter weight, brighter screen, and better battery life. In addition to this streamlined design, its prolific subset of casual games appealed to the masses, such as the "Brain Age" series. Meanwhile, "New Super Mario Bros." provided a substantial addition to the "Mario" series when it was launched to the top of sales charts. The successful direction of the Nintendo DS had a big influence on Nintendo's next home console (including the common Nintendo Wi-Fi Connection), which had been codenamed "Revolution" and was now renamed to "Wii". In August 2006, Nintendo published ES, a now-dormant, open source research operating system project designed around web application integration but for no specific purpose.
