Alternatives to AdWords and AdSense

If you're looking for ad networks - this post has a very detailed list with a nice feature comparison table...

the post is fairly old (some networks might be missing and some mentioned may have ceased operating)...but could point you in the right direction....to get your hunt started.

Thanks Rene,

I think this is the type of list I was hoping for. 

Maybe asking for a "definitive" list was a bit ambitious but this will be a good reference..    

 

So, James, are you looking for monetization as in AdSense or or advertising as in AdWords?  Please don't say both! ;-)

One definitive list to a customer!

Thanks George - not looking to monetize or advertise anything myself, just trying to improve my general knowledge of what's out there. Like many people who aren't experts in online advertising, AdSense and AdWords are about the only choices that I know of. 

My commercial motivation in asking the question is to be able to give better quality answers when clients ask me about advertising. Also to help me flesh out a couple of glossary entries.
