Abstract: A single advertisement presented within a web page can be comprised of individual components: “ad beans”. Each ad bean can be directed to a single task and multiple ad beans can be combined within an advertising structure to provide a nearly limitless set of combinations and associated functionality. An advertising structure can act as a host for ad beans and can obtain the ad beans on a real-time basis from a remote source. The ad beans themselves can likewise obtain information on a real-time basis, such as from either the same, or a different, remote host. A single entity can thereby aggregate purchases of advertising such that the aggregator's purchase of advertising can be subsequently divided among differing entities such that each individual entity need only purchase a minimum amount of advertising from the aggregator that can be substantially lower than the minimum amount of advertising traditionally sold by publishers.
