Late last night, Microsoft sent word that they've reached an Xbox 360 install base milestone, announcing that by 2008's end they have been able to sell 28 million consoles worldwide. That's an increase of around 10 million consoles since last January, don'tcha know.

On top of the 28 million install base news, Microsoft proudly informed us that 2008 saw an 84% increase in year-over-year online consumer spending, that the Xbox Live community has ballooned to 17 million members and that over $1 billion has been spent on Xbox Live since its launch in 2005. High fives all around!
