Here is a (growing) list of all internet advertisement networks for you to check out. Although this list is geared at publishers (people looking to make money from displaying ads), it is also equally useful for those of you looking to advertise your website.
CPM (Cost Per Thousand Impressions) Networks
TribalFusion - Site must have 2,000+ uniques/day, and must be regularly updated.
ValueClick - Supports other advertisement strategies such as pop-ups.
CasaleMedia - Websites must be under a root domain (www.something.com) and have atleast 10,000 unique visitors per month.
BurstMedia - Seems to be more exclusive than other similar networks.
IACAdvertising - Doesn’t seem to support 3rd-part publishers. Useful for people looking to advertise.
Advertising.com - Claims to be world’s biggest internet advertising network.
Bannerconnect
RealTechNetwork - Website looks a bit unprofessional, payment available through paypal.
Interclick
RightMedia
CPC (Cost Per Click) Networks
Google Adsense - Probably the internet’s most well known publisher solution.
Yahoo Publisher - Yahoo!’s answer to Adsense. Only available in the US.
Bidvertiser - Payment available through paypal (!).
Adbrite - Between-page ads as well as standard ads (I personally don’t like these but they might be more profitable, if they don’t piss off your visitors).
Chitika - Shopping-related ads.
Kontera - “In-Text” advertisements.
Clicksor - Supports adult content (i think?).
This list will be updated as I encounter more advertisement opportunities/networks, so check back every now and then!
The only ad network I have ever had success with was ViralyticsMedia.com. They are more of a site repping company, but if you can get in with them they are pretty solid. Customer support sucks, but they pay well.
