NPDs Look Back on December, 2007
Joystiq has the NPD numbers for the entire year of 2007 and (of course) December. Last year was a banner year for games, with the industry as a whole coming close to cracking $18 billion in sales. The big winner was the Wii, of course, with some 6 million units sold over the course of the year. The 360 sold about four and a half million, and the PS3 sold about two and a half. The big software seller was (un-shockingly) Halo 3, at 4.82 million sold, with Wii Play close behind at 4.12m. Here are the software numbers for December: "Call of Duty 4: Modern Warfare (Xbox 360) -- 1.47m, Super Mario Galaxy (Wii) -- 1.40m, Guitar Hero III: Legends of Rock (PS2) -- 1.25m, Wii Play w/ Remote (Wii) -- 1.08m, Assassin's Creed (Xbox 360) -- 894K, Halo 3 (Xbox 360) -- 743K, Brain Age 2 (DS) -- 660K, Madden NFL 08 (PS2) -- 655K, Guitar Hero III: Legends of Rock (Xbox 360) -- 625K, Mario and Sonic at the Olympic Games (Wii) -- 613K"
...it kind of bugs me that they everyone includes WiiPlay in the best seller lists for 2007....the ONLY reason people bought it is because it included a Wiimote and was only $10 more than a Wiimote by itself...I personally feel that if it didn't include a Wiimote, it wouldn't have sold even a quarter of the number of copies sold...

National Purchase Diary. Most people that pay attention to these numbers don't know / care about that though.
The group tracks product sales and sells this information. Its pretty much recognized as the most respectible source of this type of information, but it isn't completely accurate. Walmart, for example, refuses to take part in NPD data collection.
Hope that helps.
