For the sixth month in a row, Microsoft’s Xbox 360 led video game console sales with 1.37 million units sold in November, according to NPD Group, an independent market research firm.

New NPD Group research also shows that Xbox 360 was the only console to show double digit year-to-date growth at 42 percent, making it the fastest-growing console in 2010. In addition, 50 percent of spending at retail in November for current generation consoles was on the Xbox 360 platform.

During the month of November, four of the top 10 console game titles were for Xbox 360, including: “Call of Duty: Black Ops,” “Fable III,” “Assassin’s Creed Brotherhood” and “Halo: Reach.” “Call of Duty: Black Ops” for Xbox 360 was the number one selling console game in November.

Today’s announcement follows closely on the heels of news in late November that more than 2.5 million Kinect game sensors for the Xbox 360 were sold within 25 days of the Kinect’s launch.

Popular games for the Kinect include “Kinect Sports” and “Dance Central,” according to NPD Group.
