From the LA Times:

"Sales of video and computer games fell a steep 16% last month, to $735.4 million, compared with $875.7 million a year earlier, according to figures released Thursday afternoon by the market research firm NPD Group.

While the popularity of Nintendo's new 3DS handheld console helped to drive hardware sales up 12% to $494.5 million in March, that wasn't enough to compensate for the slide in software sales. When combined with sales of game accessories such as Microsoft's Kinect and Sony's Move motion controllers, overall game industry sales were $1.53 billion last month, down 4% from $1.58 billion in March 2010."
