Which brands own their own factories?

[Crocodile]

is there anyone here who knows anything about this. Back in the day for example Pro Kennex was a manufacturer. They made their own racquets plus made racquets for other companies as well. I don't know how it is now.
These days there are quite a few companies that are marketing machines but I guess you could say they out source their manufacturing from somewhere else, usually a factory from China.
I assume that Yonex is a manufacturer with stuff being made in Japan.
I wonder how many brands use the same factory? Any thoughts on this ?
