AdBrite

Adbrite is a well known internet marketplace. Unlike Google’s AdSense, this service is more based on selling of your ad space directly to your visitors. You have to have working site to be approved for AdBrite service…and actually that is all. They say your site may not be pornographical, with adult content etc tho experience says something else. AdBrite is really not as strict as AdSense. So if you have site with content that is a bit on the edge, try AdBrite.
You can sell text ads, banner ads, full page ads, InVideo, Inline ads and BritPic. Full Page Ads are full-page interactive ads containing an advertiser’s landing page or branding message. Full Page Ads appear in the main browser window between two pages of a publisher’s site, usually after a visitor’s third pageview. BritPic allows you to make money with your images by showing text ads upon image roll over with a cursor.
If for some reason AdBrite ads don’t suit you, you still can sign up to their refferal program.
