Radio presenters (a.k.a Disk Jockey, Radio Announcer, Radio Broadcaster) are the public voice of commercial, public and community radio stations. They compile and present radio programs to the public on a range of topics and with a specific musical or topical focus that may vary according to the type of station for which they work or their particular skills or areas of interest. Their on-air presentation may focus more on a particular style of music, on interviewing and talkback, or on a specific topic like sports, cooking, current affairs or gardening.
