The contributions of this volume illuminate the transformation of internal communication from theoretical, empirical, and reflective perspectives, discussing its significance for the field of research. Internal communication has gained importance in recent years. The conditions for communication within and from organizations have changed. For instance, the boundaries between internal and external communication are increasingly blurring, and the demands and expectations of employees regarding internal information and dialogue processes are rising. With this transformation, questions about new functions, goals, and roles, as well as the media of employee and leadership communication, are becoming more significant. In this context, new points of connection are emerging for PR and organizational communication research.
