Digital Signage is the use of digitally powered signs such as plasma display panels, liquid crystal displays (LCDs), kiosk stations, and computer monitors to replace and enhance traditional media. Digital signage is new media and has much more in common with the web than the static sign that it replaces. Digital display networks get the message across in a way that static posters and billboards never could.

Large, flat panel, plasmas and LCD screens are now everywhere, and they are grabbing advertising share from more traditional forms of advertising. Unlike television commercials which are broadcast to large audiences in their homes, digital signage is narrowcast to select audiences at the point of purchase as they are reaching for their wallets.
