[Cabin in the Woods] where did the monsters come from and when did the organization appear?

They're a globalish organization that go around capturing them to enable saving the world and keeping the old one asleep. They mention that the things that enabled them to do this are legends and rituals all over the world that predate the organization. It's unclear when they organized and banded together. It's also possible they operate separately and cooperatively in lieu of being one big cohesive organization. 

Considering that there doesn't seem to be one organization managing how they do anything I'd subscribe to that theory. They had to be TOLD that a bunch of other people failed. Most likely because they operate independently and not that one single organization above is coordinating them at all together.
