Well, what a difference a couple of months and a holiday season can make. Just after finding that the video game console market shrunk by a fifth in October, NPD is now back with a new report that finds that December was the video game industry's "biggest sales month ever." Specifically, the group found that console sales jumped 4% compared to last December, with the Nintendo Wii unsurprisingly leading the way with 3.81 million units moved (up from 2.15 million the previous year). That's followed by the collective DS offerings at 3.31 million and, somewhat surprisingly, the PlayStation 3, which racked up sales of 1.36 million (its first time cracking the one million mark) compared to the Xbox 360's 1.31 million. Of course, no one's expecting sales to stay at quite that lofty level, but NPD says that the spike in December sales might well indicate that 2010 could be a recovery year.
