Video game sales in the United States in 2010 were about the same as they were in 2009, according to a market research group. While sales of portable, console, and PC games down about five percent, the sale of used games, digital downloads, games for smart phones, and games played over social networks increased to keep the overall sales figures around $15.5 billion. The Xbox 360 was the only console to sell more units in 2010 than 2009, perhaps thanks to the debut of Kinect, which sold over 8 million units in the last two months of the year. [AP]
