This issue of Media International Australia explores public service media as increasingly organised via hybrid arrangements that function at any given time according to diverse technologies, politics, people and economies, with the aim of understanding how these hybrid arrangements work and their consequences for the organisation of public media. The articles offer particular examples of hybrid arrangements at work in public service media institutions, and explore a range of questions relating to such arrangements. They also examine diverse examples of hybridity that arise when public service media strive to retain their heritage brand values while responding to new regulatory and economic environments.
