How do we cut out the middle man paid per click?

I know how paid per click and paid traffic works from buyer perspective. But does anyone know how people get the traffic to send in the first place? I mean do they just simply get a better price and resell it to us or do they actually know a way to get the traffic to send us?

Thanks in advance.
