internet billboards

The name for the modern version of a point-of-purchase display, internet billboards use net technology to advertise in retail stores (such as department stores) or for menus (like in coffee shops in the real world. 

They deliver precisely targeted messages to consumers via high-definition, flat-screen displays and can rotate based on timers. The stores control the ads via desktop computers that are connected to the Internet via broadband connections. A retailer can update images and ad campaigns in real time or set them to times to display lunch items after breakfast is over.
