Labor-and material-intensive, static, traditional advertising signage, such as posters and billboards, is being replaced by flat monitor screens and quite-active digital content, often in a network, controlled from nearby or afar, often via the Internet, from any imaginable global location. Non-commercial digital displays offer huge upside potential, as well. Projections of revenue growth in the digital signage industry hit $2.6 billion (yes, billion!) by year-end 2010.1

What Is Digital Signage? For most people, the first key message to understand about digital signage is, just what is it? Indeed, as a technology and as a communications medium, it is so relatively new, undeveloped, and untested, that most both inside and outside the industry of digital signage cannot adequately describe its features and capabilities.
