Abstract: A system is disclosed for displaying advertisements on a plurality of display monitors where each display monitor is associated with and mechanically coupled to a traffic signal. The system includes a plurality of display computers where each display computer is operatively connected to one of the display monitors for providing video or other digital content information to the display monitor to be displayed. A wide area network is operatively coupled to the display computer for use in transmitting video and other information to the display computer. A local area network provides video and other information to the display computers via the wide area network, and a router is operatively connected between the local area and wide area networks for directing information from the local area network to said display computers. The system has a display (preferably rectangular) that displays the traffic signal in the same frame as the advertisement display.
