Nintendo's 3DS handheld has passed 4.5 million sales in the United States since its launch last March, the company has announced.
It means that, despite its slow start, 3DS sold almost twice as many units in its first year on shelves as its predecessor: first-year DS sales totalled 2.3 million. 3DS has brought in $1.2 billion in revenue, compared to DS's $540 million.
Nintendo Of America president Reggie Fils-Aime said: "Nintendo 3DS closes its first year with a lengthy list of accomplishments but we're still just scratching the surface.
"With a massive lineup of first and thirdparty games, and more on the way, a budding library of entertainment options and an engaged and growing installed base, Nintendo 3DS has an incredibly bright future. We're just getting started, but this platform is built for the long haul."
