They haven't been profitable in a long time for many reasons. One was that they took such a massive loss on PS3 hardware, which initially supported BC but they removed it to cut costs. Also because they used BDROM and because their TVs are selling at a loss while Samsung/Sharp/Pioneer/Panasonic/Toshiba/LG/others have taken over the mid to low range TVs.
You can google to fact check stuff like this by the way.
SNE is their stock. Google results for
"sony massive loss".
They'll probably have to restructure. But their performance is higher risk compared to Nintendo and Microsoft, which are very profitable most of the time.
