Game Boy Advance in the context of "Nintendo Classics"

The Nintendo DS is a foldable handheld game console produced by Nintendo, released worldwide between 2004 and 2005. The "DS" in the name is an initialism for "Developers' System" or "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 Nintendo DS supported wireless connectivity for local multiplayer over short distances, as well as online play through the now-defunct Nintendo Wi-Fi Connection service. During the seventh generation of video game consoles, its primary competitor was Sony's PlayStation Portable.

Prior to release, Nintendo marketed the DS as an experimental "third pillar" in its console lineup, intended to complement the Game Boy Advance family and the GameCube. However, backward compatibility with Game Boy Advance titles and strong sales led it to be widely regarded as the successor to the Game Boy line. On March 2, 2006, Nintendo released the Nintendo DS Lite, a slimmer and lighter redesign featuring brighter screens and improved battery life. The system was later followed by the Nintendo DSi, released on November 1, 2008, which introduced additional enhancements such as dual digital cameras and digital distribution of games, while removing backward compatibility with Game Boy Advance titles.

Satoru Okada (岡田 智 Okada Satoru, born January 10, 1947) is the former general manager of Nintendo Research & Engineering, the division designing and developing Nintendo handheld game consoles. He is best known for creating the original Game Boy and its successors. He was also assistant producer and director of and contributor to several Nintendo games, notably Metroid, released for the Nintendo Entertainment System in 1986.

Okada entered Nintendo in 1969 and went on to work as an engineer at Nintendo Research & Development 1 with Gunpei Yokoi, who developed the hugely successful Game & Watch and Game Boy handheld game consoles. In 1996, Yokoi left Nintendo which caused R&D1 to split, its engineers creating a portable hardware division of which Okada became the general manager. His team lacked Yokoi but nevertheless developed hugely successful handheld consoles: the Game Boy Color, Game Boy Advance, Game Boy Advance SP and Nintendo DS. Okada initially opposed the Nintendo DS' dual-screen design but was overruled by Hiroshi Yamauchi.

The Nintendo GameCube is a home video game console developed and marketed by Nintendo. It was released in Japan on September 14, 2001, in North America on November 18, 2001, in Europe on May 3, 2002, in Australia on May 17, 2002, in Brazil on August 23, 2002, and in South Korea on December 14, 2002. It is the successor to the Nintendo 64. As a sixth-generation console, the GameCube primarily competed with Sony's PlayStation 2, Sega's Dreamcast, and Microsoft's Xbox.

Nintendo began developing the GameCube in 1998 after entering a partnership with ArtX to design a graphics processing unit. The console was formally announced under the codename "Dolphin" the following year and was released in 2001 as the GameCube. It is based on PowerPC. It is Nintendo's first console to use its own optical discs instead of ROM cartridges, supplemented by writable memory cards for saved games. Unlike its competitors, it is solely focused on gaming and does not play mass media like DVD or CD. The console supports limited online gaming for a few games via a GameCube broadband or modem adapter and can connect to a Game Boy Advance with a link cable for exclusive in-game features using the handheld as a second screen and controller. The GameCube supports e-Reader cards to unlock special features in a few games. The Game Boy Player add-on runs Game Boy, Game Boy Color and Game Boy Advance cartridge games.

2001 saw many sequels and prequels in video games, such as Madden NFL 2002, NBA Live 2002, NBA 2K2, WWF Smackdown! Just Bring It, Capcom vs. SNK 2, Crazy Taxi 2, Dead or Alive 3, Final Fantasy X, Gran Turismo 3: A-Spec, Grand Theft Auto III, Metal Gear Solid 2: Sons of Liberty, Myst III: Exile, Silent Hill 2, Sonic Adventure 2, SSX Tricky, Super Smash Bros. Melee, Tekken 4, Tony Hawk's Pro Skater 3, and Virtua Fighter 4. New intellectual properties include Phoenix Wright: Ace Attorney, Advance Wars, Animal Crossing, Burnout, Gothic, Black & White, Devil May Cry, Fatal Frame, Ghost Recon, Halo: Combat Evolved, Jak and Daxter, Max Payne, Oni, Onimusha: Warlords, Operation Flashpoint, Pikmin, Pro Evolution Soccer, Red Faction, Serious Sam, and Tropico.

Three major video game systems were released in 2001: the GameCube and the Game Boy Advance by Nintendo, and the Xbox by Microsoft. Sega, which had been a major competitor in the video game hardware market to this point, ended its involvement in the market after the failure of the Dreamcast.
