It's all of the major networks including Google's own affiliate network.

I was afraid that name will come up... I've had some really bad things happened to my sites last year a week or so after rolling out Google's own affiliate network ads. There's not good way to know for sure if it contributed but I won't ever be using GAN network again. I haven't earned a penny from it anyhow.
