This has to be one of the most interesting figures i've seen, no joke. Where did you got them?
Or im understanding wrong? So after all this time and just factoring Xbox business MS only have made 250 mm?
I keep
a lazy record of Nintendo/Sony/Microsoft earnings reports (with citations in the cell comments showing sources). Specifically, it remembers the
operating income of the divisions in which the systems sell. For Microsoft, it's the "Entertainment and Devices" division. For Sony, it was the "Game" division then the "Networked Products & Services" division then the "Consumer Products & Services" division. For Nintendo… it's Nintendo.
NB: Microsoft's division also contains the Zune, which sold poorly. Sony's devices also contain things like.. I dunno, the Walkman is still a thing, right?… as well as the PS2, whose ongoing sales likely made the losses seem less bad than they were. Also the massive pre-gen R&D costs are not figured in.
There are problems with my method of record keeping. For one thing, they often go back later on and change numbers, probably due to inflation and so forth. But it's close enough to being accurate to work with on a basic level.
For Microsoft, they were basically bleeding cash indiscriminately from launch until and including the middle of 2007 (that was, I think, when they took that billion dollar RROD charge). Then they
generally started making a profit with losses every few quarters. And from the middle of 2010 until the end of 2011 they were consistently profiting. I was surprised when they posted a loss this quarter, but it's probably partly (largely?) due to R&D for the upcoming generation.
They're in a really good position now. It just took a while for their profits to overcome the initial losses.
Not shown: I think the Xbox Classic was an overall loss of four billion dollars, but I don't have the numbers. My focus was an attempt to measure profitability of current gen, though (also because choosing this particular time span unfairly benefits Nintendo in charts ^_^ ).
edit: There's also a "By Year" tab which shows everything by calendar year, including the totals for the Big Three added together, but the values were generally pasted in from my original spreadsheet, so I'd have to update and double check them when I have the time.
edit²: Regarding your original question, if you count the original Xbox, Microsoft is probably still heavily in the red, but current, ongoing profits are generally considered more pertinent to a company's health than averaging out past performance, so it is not something people really harp on.
