In the United Kingdom the term "public service broadcasting" (PSB) refers to broadcasting intended for the public benefit rather than for purely commercial concerns. The communications regulator Ofcom, requires that certain television and radio broadcasters fulfil certain requirements as part of their licence to broadcast. All of the BBC's television and radio stations have a public service remit, even those that only broadcast digitally. Additionally, all stations broadcast on terrestrial analogue television - the regional Channel 3 companies (the ITV Network), GMTV, Channel 4, S4C in Wales, and Five - are obliged to provide public service programming as they can be viewed freely almost anywhere nationwide. Commercial radio also has public service obligations. However, the requirements imposed for commercial radio are generally fewer, normally requiring only a minimum level of news.
