This chapter examines the existence and nature of co-regulation models as a horizontal extension of national statutory media regulation. In light of transnational processes such as technical convergence and Europeanisation, new perspectives and forms of media regulation and media governance are needed. Traditionally, media regulation has long centred on command and control by governments. The concept comprises forms of statutory media regulation, forms of co-regulation where industry players work together with state actors, and it emphasises the need to involve civil society. The chapter assesses whether representatives of both civil society, such as non-governmental organisations, and private actors, such as industry stakeholders, are involved in the supervisory and advisory bodies of the media regulatory agencies and public service broadcasting providers. The inclusion of media organisations and civil society representatives into new regulatory models seems more effective than pure state regulation with regard to ensuring that public interest objectives are achieved.
