Abstract: A method and system are provided for presenting highly targeted advertisements to the user of a mobile device running an application which incorporates a Mobile Agent designed according to the disclosure. The Mobile Agent communicates with an advertising server that analyzes information received from the Mobile Agent, and selects advertisements for transmission to the Mobile Agent and presentation to the user. The disclosure uses the intended audiences of the available advertisements, the nature of the application, and the user's history of responses to previous advertisements to select advertisements that are likely to be considered useful by the user. The disclosure further uses information about the mobile device's position and its direction and speed of motion, and the locations of places of business associated with the available advertisements, to select advertisements for places of business that are proximate to the user's position, predicted destination, or predicted route.
