Most public displays deployed today literally disappear: people have become so accustomed to their low utility that they have become highly skilled at ignoring them. In contrast to Mark Weiser’s influential vision of the ``Computer for the 21st Century,’’ however, public displays of the 21st century should not disappear. Rather they should become the backbone of a new global communications medium that provides valuable information to viewers who are motivated to actively embrace the technology.

In this talk I will argue that the transformation of public displays to this new communications medium requires significant innovation that can only occur through opening display networks to applications and content from a wide range of sources, such as city officials, local residents, and visitors. Based on this idea I will discuss our work in creating the building blocks to realise this vision and our experiences of running an experimental public display system for over seven years.
