> popunder (is there any point to those ?) I recall reading that the original intention of popunder ads was to provide a degree of separation between the site content and the ad, as you see the ad. isolated rather than directly next to the site content. By doing so, the ad. provider has to worry less about their brand appearing next to content they may find objectionable.
