Nintendo announced New Super Mario Bros Wii has sold more than 2 million copies in North America.
"Nintendo products top Amazon.com’s Most Wished For and Most Gifted lists for video games, and Wii remains at or near the top of the most-searched for video game terms on Yahoo!" said NoA sales and marketing VP Cammie Dunaway. "As families and friends gather for the holidays, Nintendo games offer the best shared experiences."
