Abstract: The invention comprises a method and system for providing capabilities to program, control and display both messages and rich media contents on a network of information narrowcasting appliances from a remote location. The information narrowcasting appliance is a computer system that includes an embedded PC, a system-on-chip microprocessor, a wireless communications card, and a combination of digital LED displays and LCD displays. The displays are a self-contained structure, requiring no additional computer systems to control the displaying of contents or transferring of data. Additional output devices, including audio speakers, motion sensors, scent players, or RF ID sensors can be also added to enhance the level of information delivery and collection by the appliance.
