Sales of video game consoles in the U.S. hit a five-year low last month according to new data from research firm NPD Group. “May 2011 was the lowest month of sales for the industry since October 2006,” NPD analyst Anita Frazier said in a statement. “A light slate of new releases is at the heart of this month’s performance.” Combined sales of hardware, software and accessories totalled $743 million according to the firm, representing a 14% decline compared to May 2010. Software sales were down 21% from the same month a year prior to $400 million. Microsoft managed to combat the trend — and keep total console sales in May from sliding to unheard-of lows — having sold 270,000 Xbox 360 consoles, up 39% year-over-year. Take-Two Interactive’s L.A. Noire was the top-selling software title for the month.
