Abstract: A method and system of determining a viewership of a media content includes displaying a media content on an outward display device. For each vehicle in a predetermined range of the outward display device, a data packet comprising data from one or more sensors of the vehicle is received. It is determined whether the vehicle is unique based on the data packet. Upon determining from the data packet that the vehicle is unique, a dwell time of the vehicle is determined with respect to the displayed media content on the outward display device.
