A communication system capable of targeting a demographically or psychographically defined audience. A master database (20) is maintained, containing demographic and psychographic information about each audience member. This information is transmitted and stored in a channel selection/decoder (100) unit associated with each audience member's receiver. Multiple media messages are transmitted to each audience member. Accompanying the transmission is a selection profile command, which details the demographic/psychographic profile of audience members that are to receive each media message. The channel selector/decoder (100) unit associated with each member's receiver compares the selection profile with the demographic/psychographic information about the audience member and selects the appropriate media message for that audience member.
