Sales Data:

"The videogame industry experienced its biggest sales month ever, besting last December by 4%,” said NPD's Anita Frazier. “It wasn't enough, though, to compensate for the sales decline throughout the year, and so full-year sales came in 8% below last year's record-setting revenues."

Sales of videogames, which includes portable and console hardware, software and accessories, generated revenues of close to $19.66 billion during 2009, compared to $21.4 billion in 2008.
