Abstract
A GPS-based advertisement service is one which uses customer-location tracking to provide different location specific information to users via mobile devices, wherever they are and whenever it is needed. As the first step in this study, a preliminary online survey conducted to determine users' opinions and interests with regards to GPS-based advertisement systems. The results of the study led to the proposed new service called e-Brochure, which would send advertisement and promotion information for points of interest such as hotels, restaurants and all cultural sites of interests according to the user's current location.
