Microsoft has sold 67 million Xbox 360 consoles since its launch in 2005, raking in more than $56 billion at retail. Kinect has sold 19 million units and Xbox Live has 40 million members, leaving us to question what the remaining 27 million people are doing with their Xboxes if they aren't downloading games or watching video on Amazon Instant, a service announced and rolled out just today.

It would appear the current generation of gaming consoles has sustained itself on its broader entertainment options, and Xbox 360 sales have increased from years four to five, five to six and six to seven, as the above graph indicates.

"The more entertainment options we add, the more time people spend on Xbox," Microsoft said.

BTW if folks didn't notice, Amazon Instant app launched on the 360 today.

If you notice on the graph, since Year 3 Wii started falling, and that's when the 360 started increasing. Coincidence?

Kinect sure has done wonders.

Nice!

Fortunately all 3 consoles this gen have done sufficiently well that a follow up console from any of the 3 has been pretty much garantueed after the first few years into the gen.

19 milions Kinects ? thats sure is alot.. 56 bilions is crazy...

Something is wrong here
67m 360s @199: 13.4b
17m kinects@99: 1.7b
638m games @40: 25.6b
Live for 40m x 3 @50: 6b
30m controllers @60: 1.8b
5m hard drives@99:500m wifi; 500m
:49b only7b missing.
all of these numbers are extremely conservative here as well.

What does it do?  I haven't fired up my 360 in probably a week or so.

If by increasing you mean staying constant and not increasing, then yes, I also noticed that 

It streams movies, tv shows, etc if your a Amazon Prime member(similar to netflix). You can purchase movies also.

I was trying to post this video decribing it all, but vgc got all screwy. http://www.youtube.com/watch?feature=player_embedded&v=Sg72YSD2XwM
