The market-leading game company achieved its status in part by courting users that span generations and skill levels.

Also leading in handheld consoles, its DS device began in 2004, the most recent incarnation its no-glasses 3-D version launched in 2011, the 3DS. Wii successor Wii U, featuring a controller with a touch screen, is planned for 2012.
