Job titles differ according to the type of production and the company. The newsreader, newscaster or anchorman/woman on a news programme plays the same role of linking items as the presenter of a magazine programme, the disc jockey on a radio programme, the host on a chat show or the quizmaster/mistress of a quiz show. Their function is the same, yet what they are called varies. In news programmes, for example, there are subtle distinctions between a reporter and a correspondent – reporters cover news stories generally, a correspondent has a particular area of expertise, for example education or the environment. The audience, however, simply sees or hears someone describing a situation.
