Radio plays such an important role in UK media; millions wake up to music or speech radio. During the day, it's a constant companion for many and an essential source of national and local news, information and entertainment to suit a multiplicity of tastes and cultures.

As with TV, most public service radio broadcasting is provided by the BBC with national networks and regional stations; similarly, deregulation in the sector has encouraged the development of a small number of super radio companies, currently led by Bauer, which has a substantial regional network, Global and Absolute Radio.

Many new entrants develop an interest in radio at university or college and will be familar with the Student Radio Association; hospital and community radio also provide an opportunity for would-be broadcasters, producers, presenters and technicians to 'cut their teeth'.
