SBS has been the subject of some heated debates about funding models, commercial activity, perceived 'populism' and the continued relevance of publicly funded media. These debates and challenges are not unique to SBS or to Australia. Public Service Broadcasting (PSB) in many contexts is facing a 'crisis of legitimacy' as it struggles to retain audiences in the face of new technologies, rapidly globalising media, and the rejection of traditional patterns of media usage, particularly among younger generations. Debates around commercialism and the role of PSB in the market also continue in Europe, despite the plurality of models and funding arrangements. Public broadcasters have faced accusations of irrelevance. This is particularly the case in relation to cultural diversity, as old models of representation, universalism of access and nation-building are unable to keep pace with increasingly complex and diversifying societies.
