Abstract: A mobile display system comprises one or more movable billboard displays, equipped with externally viewable display panels and a controller. The display is moved from location zone to location zone by a transporter which may comprise a person or a vehicle. The controller ascertains the display location and drives the display to generate a publicly viewable message selected for viewing within such location zone. The message is displayed pursuant to a schedule which includes date, time of day and display duration while the display is within the zone or until the display is located in another zone which is not included within the message schedule. A tiered system control network includes a plurality of fixed stations which transmit message content and scheduling data to the controller and which generate billing and other accounting records. An advertiser may communicate with the network for creating and changing message content and scheduling data.

Abstract: A mobile display system comprises one or more vehicles, e.g. taxis, buses, tractor-trailers, etc., equipped with externally viewable display panels and an on-board controller. The controller determines the vehicle location and drives the display to generate a publicly viewable message selected for viewing within such location. The message is displayed pursuant to a schedule which includes date, time of day and display duration while the vehicle is within the zone or until the vehicle is located in another zone which is not included within the message schedule. A tiered system control network includes a plurality of fixed stations which transmit message content and scheduling data to the controller and which generate billing and other accounting records.
