Abstract: Point-of-sale information distribution and presentation systems which may be controlled centrally, hierarchically or as otherwise desired in order to distribute and display audio and/or visual information selectively. The systems comprise intelligent automated devices at the point-of-sale locations, such as service stations, which may be coupled or connected to a central location by modem, other land line, satellite, or as otherwise desired. Such systems may also measure and report information that relates to actual presentation of the information, exposure of customers to the information and, if desired, customer purchases associated with their exposure to the information. Moreover, these systems may be arranged to alter the distribution or presentation of information according to environmental sensing information at point-of-sale level regionally or nationally. Overrides may be included so that the system may be employed to notify appropriate authorities in the event of an emergency.
