I don't know who they used to get their compensation before, but from reading the company's website, it seems like they take it a step further. For example, it sounds like they would police the internet. If you personally create a video, and use a GD song, they would pick up on that. I would imagine they would either tell you to take it down or send you a bill. I'm not exaclty sure how they handle the money aspect. I would also imagine they might monitor news articles for potential use in events, etc. I don't know if that is exactly right but that is what I think they do.
