They will often be hired for a programme, or series of programmes, based on their stylistic reputation. An understanding of the target audience, and what they expect, is a vital part of the role. Presenters work on all kinds of live or recorded programmes, including: news and current affairs, sport, music shows, chat shows, children’s entertainment, game shows, and specialist programmes such as travel, gardening, history and DIY. The majority of shows on television are pre-recorded, although live work is not uncommon, and in radio it is often the rule. Continuity announcers are usually live on the air to provide the vocal link between programmes, informing the audience of what is coming on in the future. They describe changes to programmes and sometimes interrupt broadcasts with urgent news or apologies for faults.
