Abstract
Changing industry practices and forms of production organization are the medium and result of co-evolutionary processes of change. The disruptive event of transforming the German TV industry into a dual system triggered a change in content production from in-house to collaborative forms in project networks which are not only highly sensitive to previous and anticipated project practices, but also to industry practices. In turn, the change in the production organization recursively influences the reproduction of industry practices. The co-evolutionary analysis is based on structuration theory.
