Advertisement vendors can be dynamically selected in response to a request from a wireless communication device. A mediation router can receive an ad request from a portal interfaced with a wireless device. Specifically, the mediation router analyzes the request and dynamically selects an ad vendor to service the request, based in part on the analysis. The selected ad vendor supplies the ad and the mediation router ensures that the portal receives the ad. The mediation router selects an ad vendor in a variety of ways including, but not limited to, business decision rules or artificial intelligence and/or a combination thereof. The mediation router further employs customer profiles that help vendors target advertisements to specific consumers and wireless devices.
