A radio and television announcer, also called as a broadcast presenter, is the public face – or voice – of programmes broadcast on television, radio and the internet. They work on a variety of platforms including national, regional, satellite and cable television, online or radio, but their role is always to entertain and inform their audiences by presenting information and/or entertainment in an accessible and attractive way. The nature of the job varies according to a programme’s subject matter, such as news, weather, sport, music, lifestyle, etc. However, the general principles remain the same: an announcer will often introduce, host (or co-host) a programme, creating links between items, introducing and interviewing guests and interacting with the audience.
