As has already been established, Nintendo is doing well for itself, shattering sales records in the United States with the Wii and Nintendo DS. And, according to Nintendo, it's 99% responsible for the industry's growth.
Nintendo highlighted that fact in its response to NPD sales data released yesterday, showing that Nintendo hardware sold more than 20 million units in the U.S. last year, with 132 million software units sold on the company's platforms. That's a considerable increase from the nearly 15 million consoles and portables it sold in 2007.
