Apparatus Pertaining to Identifying Information, Corresponding Characterizing Information, and Corresponding Modification of a Presentation that is Commonly Shared by a Plurality of End Users, and a Corresponding Method

摘要

A control circuit serves to receive data messages in conjunction with a corresponding source identifier from each of a plurality of sources (wherein the plurality of sources each have, at the time of sourcing their respective data message, a corresponding end user who is presently sharing a common presentation with others of the end users). The control circuit uses the source identifier to determine additional identifying information for at least a substantial number of these end users and then uses that additional identifying information to determine characterizing information for at least a substantial number of the end users. This characterizing information can then be used to modify the common presentation (for example, by controlling particular items of promotional content that comprise a part of the presentation).
