Yes, because clearly all advertising networks on the internet try every single affiliate program out before brokering it to advertisers. You know, to see if they can make sales with it. <-- WHAT?! You cannot be serious.
Ad networks are not in the business of sending traffic to affiliate programs. They are in the business of brokering advertising space.
I've heard this argument so many times it's ridiculous. "Well if the traffic was so great, then why would the publisher be selling it?" This is a moot point. Publishers (in mainstream or adult) sell their ad space for a variety of reasons. Pertaining specifically to affiliate programs, they would rather get paid a fair amount for their traffic and not have to wonder if they'll ever get a check from an affiliate program (just a thought).
Oh yes, why would Clear Channel sell radio advertisements to advertisers? When clearly they should be trying to advertise different affiliate programs and products to make sales for themselves. Because obviously, if they are selling radio commercial airtime, they must not have been able to monetize it. <- LOL
