Looking for list of ad-serving domains

ad domains

[sitetruth]

I'm looking for a list of ad-serving domains and their owners.
Is there any available list that covers, say, 99% of served ads?
I have the big ones like doubleclick, of course, but I'd like to get to the 99% coverage level.

Is this a tracking issue? You might have better luck on one of the marketing forums in WWW.
