You see the companies not part of the circle. Like Microsoft, T2, EA, Ubisoft, Sony and Tencent. These are really big companies and they own a bunch of other companies and make a lot of money.

As you can see, each of the big companies own several other companies. The piece of the circle under microsoft shows the companies that they own.

Also, Konami is a big company but it doesn’t make much money as the big giants shown here.
