Nintendo's Super Smash Bros. Brawl has sold more than 1.4 million copies in the U.S. in just one week, making it the fastest selling game in the game company's history.

Super Smash Bros. Brawl has made the leap from video game to cultural phenomenon, said Cammie Dunaway, Nintendo of America's executive vice president of sales & marketing.

Brawl sold more than 874,000 on March 9, and has sold at a rate of more than 120 units per minute between that launch date and March 16.

The previous game in the series, Super Smash Bros. Melee, became the best-selling Nintendo GameCube game of all time with more than 7 million copies sold worldwide.
