Abstract: The invention provides in some aspects a system for display of context-aware content that includes a server storing context-sensitive data, a player that is persistently or, at least intermittently, coupled to the server, and that is likewise coupled to a plurality of output devices—such as, for example, electronic shelf labels, personal digital assistants, mobile phones, and LCD, LED or other fixed displays. The player responds to the context of each of the plurality of output devices by obtaining from the server data germane to that context, storing that data or content germane to that context generated from that data, and driving that content to that output device for presentation thereon, wherein the player concurrently drives different content to at least two of said output devices.
