Even though it is seven years old, Microsoft’s Xbox 360 still sells millions per year.

The Xbox installed base is now 76 million, up from 70 million at the end of September of last year, said Yusuf Mehdi, who leads Microsoft’s interactive entertainment business, speaking at D: Dive Into Media this afternoon.

It’s important to Mehdi and company that Xbox isn’t just perceived as a hard-core gaming device. He offered some usage numbers to combat that assumption: 38 percent of Xbox users are women, and more than 51 percent are people who have kids.

U.S. Xbox account holders use the devices for 87 hours per month. As of last March, non-game usage — fitness, entertainment content from partners like HBO and Netflix, etc. — started outpacing game usage on a yearly basis. There was 57 percent year-over-year growth in entertainment usage.

Microsoft also sent over some more stats: 24 million Kinects have been sold, up from 20 million last year, and there are 46 million Xbox Live accounts, up from 40 million
