Advertising zones are defined within the geographic region. Users of mobile computing platforms are provided with geographically-related services that use the geographic database. As users of the mobile computing platforms travel in the geographic region, the locations of the mobile computing platforms are determined. Demographic information of the mobile computing platform is associated with the position of the mobile computing platform. A market research record identifies which of the mobile computing platforms are located within or passing through one of the advertising zones. <P>COPYRIGHT: (C)2009,JPO&INPIT |
