Abstract: Providing collected profiles by selecting one or more media properties and providing to each selected media property at least one profile attribute in a manner sufficient to enable the selected media property to electronically associate the provided profile attribute with the electronic visitor. Selected media properties can be a subset of one or more identified media properties. The media properties are selected or identified automatically, responsive to receiving current profile information about the visitor, among a multitude of media properties, based on a comparison of current and/or previous profile information received with previously received individualized requests for specific profiles, kinds of profiles, or profiles having specific attributes of interest to each of the media properties. A media property can be selected among those identified based on a media property selection history.
