This one was pretty new. Similar to AllAdvantage, you opened up their software and viewed banner ads while you were online. Paying you, however, was different. UtopiAd didn't have a fixed per hour rate. Instead, they payed you depending on how many banner ads you view.
Webmasters are probably familiar with how it's run.
Several web sites sell banner ad space, and charge per 1,000 exposures. With UtopiAd, you are paid a portion of this. You also can refer people and get a percentage of what they earn. The banner ads software hasn't been released yet, so I can't really tell you how good it is. I signed up for ePipo pretty soon after AllAdvantage.
