A platform for the delivery of dynamic, interactive audio advertisements played in response to a consumer initiated request for information via a telephone. The platform invention provides advertising supported information services that are related to a geographic location associated with a response to a consumer initiated request. In one specific embodiment, at a customer station, a consumer dials an information access number and is connected to a call processing system. The call processing system receives a request for information from the consumer, and determines a response. The response is then further processed to determine a geographic location associated with the response. An advertisement is then selected that is associated with the geographic location of the response (as opposed to the geographic location specified in request, or as opposed to the geographic location of the consumer, which may not necessarily be the same).
