AdBrite

AdBrite, billing itself "the Internet's ad marketplace", Internet advertising network claims a target base of 100 million users across 110,000 sites. The network offers a variety of different advertising options for publishers and advertisers including text ads, banners, inline ads, full-page ads and in-image ads. Primarily CPC. Referral program, but kinda short-term.

From the website, for publishers:

"AdBrite can help you monetize your site with advertising that fits the content and user base of your site. Our base of advertisers includes top brands like Live Nation, GM, AT&T and Verizon—at the same time, AdBrite serves ads on nearly 1 billion pages daily, providing massive scale opportunities... In addition to text and banner ads, AdBrite offers advanced options like our Full Page Ad, BritePic, and Inline ads. These formats will allow you to show high-value ads without losing site real estate—and the multimedia formats let you take advantage of the photos and video clips on your site. Bottom line, you’ll earn more than with the standard options provided by most ad networks."

From the website, for advertisers:

"AdBrite serves ads on nearly 1 billion pageviews daily... OTEx (Open Targeting Exchange) ensures your ad will benefit from leading edge targeting... AdBrite offers advertisers unparalleled transparency and control. You’ll see every site your ad has run on, and can allocate more budget to better-performing sites, or pause under-performing sites."

Net 60 payment, which is slow as hell, but if the pay is good it may be worth the wait.

No clear payment terms or site requirements, although the info may be be buried somewhere in there. Have a look and decide for yourself.
