The Center on Organizational Innovation promotes research and experimentation with new forms of collaboration, communication, and coordination afforded by emerging interactive technologies. At mid-century, organizational analysts at Columbia University, including Peter Blau, Alvin Gouldner, Paul Lazarsfeld, and Robert Merton, charted the rise of bureaucratic organizations and the emergence of mass communication through case studies of work groups and the demographics of audience reception. In our new century, we chart the emergence of collaborative organizational forms in an era when social interaction moves seamlessly between encounters face to face and at the digital interface.
