Universities are pivotal in contemporary knowledge societies, bridging science and society. Amidst societal transformations, communication has become crucial for higher education institutions (HEIs). Yet, research on university communication is limited, with few studies capturing long-term developments. This qualitative study addresses this gap by examining changes in university communication departments over the past decade in Switzerland. Semi-structured interviews with 30 communication practitioners and university leaders in eight HEIs reveal that university communication has diversified with regard to digital channels and stakeholders, intensified in terms of personnel and output, and professionalized. Moreover, some, albeit not all communication departments have increasingly aligned their communication strategies with university strategies. Despite the fact that “everything has changed”, differences exist among various types and clusters of universities. This study contributes to understanding how and why long-term changes in institutional science communication emerge. It also offers insights for communication practitioners for enhancing university communication processes and structures.
