Originating from the field of organizational communication studies, the Communication Constitutes Organization (CCO) perspective offers a communication-centered explanation of organizational phenomena that emerge in and are sustained and transformed by practices of communication. We provide an overview of this perspective in research and its historical development, structuring our article according to three streams of current CCO scholarship focused respectively on the communicative constitution of organization as an entity/actor, organizing as a process/practice, and organizationality as a gradual attribute. We present key concepts and findings of these streams of scholarship and elucidate their implications for corporate communication research.
