Open Display Networks
Open Display Networks propose that digital displays in public space can work as an open communications medium — the way radio, television and the web did before them — where applications, services and content from multiple providers coexist on shared infrastructure instead of competing for one vendor's playlist.
The European research programme that established this framing, FP7 PD-Net (Grant Agreement 244011, 2010–2013), explicitly named culture, public space and civic information as priority domains. It left behind an active international community: the PerDis symposium series, opendisplays.net, and a substantial body of doctoral work on the subject.
