Digital signage is a form of electronic display that shows information, advertising and other messages. Digital signs (such as LCD, LED or plasma displays) can be found in public and private environments and many building across campus.
"Content", in the context of digital signage, is the name used to describe anything designed and shown on the displays. Content can be anything, including text, images, animations, video and audio.
The benefits of digital signage over static signs are that the content can be exchanged more easily, animations can be shown, the displays can adapt to the context and audience, even interactively, and deliver targeted messages to specific locations at specific times. Digital signage can offer superior return on investment compared to temporary and/or traditional signs or posters.
The term "digital signage" has taken hold though it may also be referred to by the terms "narrowcasting", "screen media", "place-based media", "digital merchandising", "digital media networks", "digital out-of-home" or "captive audience networks".
