Concerto is a type of digital signage, which is essentially a fancy term for the use of digital screens, such as televisions, to broadcast specific messages about events, services, and other noteworthy items. But Concerto sets itself apart from many other signage platforms in a couple big ways: first, it’s free for anyone to use and deploy, it’s designed in a unique way to facilitate the sharing of messages across large communities, and it’s targeted at big public spaces, such as universities and townships.
