Prior to its release, the Nintendo DS was marketed as an experimental, "third pillar" in Nintendo's console lineup, meant to complement the Game Boy Advance and GameCube. However, backward compatibility with Game Boy Advance titles and strong sales ultimately established it as the successor to the Game Boy series. On March 2, 2006, Nintendo launched the Nintendo DS Lite, a slimmer and lighter redesign of the original Nintendo DS with brighter screens. On November 1, 2008, Nintendo released the Nintendo DSi, another redesign with several hardware improvements and new features. All Nintendo DS models combined have sold 154.02 million units,making it the best selling handheld game console to date, and the second best selling video game console of all time behind Sony's PlayStation 2. The Nintendo DS line was succeeded by the Nintendo 3DS family in 2011, which maintains backward compatibility with nearly all Nintendo DS software.
