Despite enjoying a series of advantages and privileges, including access to public funding and technical infrastructure, as well as a special regulatory framework allowing them to reach almost the entire population, public service media (PSM) have historically faced a number of challenges. These include opposition from privately held media and various political parties, mounting criticism from audiences, and incessant pressures from state authorities. Some have been more successful than others in defending themselves against these attacks. Some PSM institutions have gained a high level of trust as a result of their ability to maintain a balanced approach to political coverage. Some are recognised for the quality of their news content. However, some other organisations have lost credibility and audience share as a result of various pressures. The platformisation trend has had a particularly disruptive impact on public service media (PSM) organisations. The challenge of adapting to the new digital landscape has been significant, requiring careful navigation to maintain the core values that guide their operations, as defined by the European Broadcasting Union (EBU): universality, independence, excellence, diversity, accountability and innovation. This article employs a recently developed framework for examining PSM and draws upon field research to analyse the transformation of PSM in response to platformisation-related pressures in four European countries: Austria, Romania, Spain and the United Kingdom.
