ProWebSurfer have developed the concept of a Personal Ad Server. Unlike most ad networks, which try to guess how best to place ads in the right place, a Personal Ad Server puts the user at the center of the ad network. This concept allows a user to set up their own preferences for what, when and how advertising comes to them. Although this limits the ability of advertisers to target consumers, it ultimately enables closer targeting, more efficient advertising, and happier customers.
