Is Microsoft the only one of the big 3 who knows how to run a video game business at this point?

If i can make an extra 100 dollars a month by putting ads on my youtube channel, imagine how much Microsoft is making with Ads on their dashboard, including LIVE fee. Just 2 examples, now you know how they have enough money to campaign Kinect and buy timed exclusive rights etc.
