Digital signage systems deliver customized media playlists to one or more digital screens, enabling a network manager to display targeted information to a specific audience at a specific place and time. Relative to traditional signs, digital signage messages can be easily customized, changed out quickly and inexpensively and delivered to many displays at once. Digital signage is often used to present a custom-tailored content mix, including product promotions, timely news, and upcoming events. Screens can be mounted on walls, ceilings, shelving systems, or aisle endcaps, or integrated into freestanding displays and kiosks. Digital signs are used in a wide variety of applications ranging from targeted retail advertising to internal employee communications and remote training.
