Public service broadcasting is provided for in Part 7 of the Broadcasting Act 2009, which sets out the principal objects of the public service broadcasting corporations, RTÉ and TG4. These objects provide the companies' statutory mandates and reflect national policy on public service broadcasting. Principally, this includes the provision of national, free-to-air television and sound broadcasting services to the whole community of Ireland.
The objects also include the provision of a broad range of other services that are seen as fundamental to the role of a public service broadcaster in a modern and changing media landscape, such as the provision of online media services.
I consider these objects and thus the definition of public service broadcasting fit for purpose.
