A radio personality (American English) or radio presenter (British English) is a person who has an on-air position in radio broadcasting. A radio personality who hosts a radio show is also known as a radio host, and in India and Pakistan as a radio jockey. Radio personalities who introduce and play individual selections of recorded music are known as disc jockeys or "DJs" for short. Broadcast radio personalities may include talk radio hosts, AM/FM radio show hosts, and satellite radio program hosts.
A radio personality can be someone who introduces and discusses genres of music; hosts a talk radio show that may take calls from listeners; interviews celebrities or guests; or gives news, weather, sports, or traffic information. The radio personality may broadcast live or use voice-tracking techniques. Increasingly in the 2010s, radio personalities are expected to supplement their on-air work by posting information online, such as on a blog or on another web forum. This may be either to generate additional revenue or connect with listeners. With the exception of small or rural radio stations, much of music radio broadcasting is done by broadcast automation, a computer-controlled playlist airing MP3 audio files which contain the entire program consisting of music, commercials, and a radio announcer's pre-recorded comments.
In the past, the term "disc jockey" (or "DJ") was exclusively used to describe on-air radio personalities who played recorded music and hosted radio shows that featured popular music.  Unlike the modern club DJ who uses beatmatching to mix transitions between songs to create continuous play, radio DJs played individual songs or music tracks while voicing announcements, introductions, comments, jokes, and commercials in between each song or short series of songs. During the 1950s, '60s and '70s, radio DJs exerted considerable influence on popular music, especially during the Top 40 radio era, because of their ability to introduce new music to the radio audience and promote or control which songs would be given airplay.
Although radio personalities who specialized in news or talk programs such as Dorothy Kilgallen and Walter Winchell existed since the early days of radio, exclusive talk radio formats emerged and multiplied in the 1960s, as telephone call in shows, interviews, news, and public affairs became more popular. In New York, WINS (AM) switched to a talk format in 1965, and WCBS (AM) followed two years later. Early talk radio personalities included Bruce Williams and Sally Jesse Raphael. The growth of sports talk radio began in the 1960s, and resulted in the first all-sports station in the US, WFAN (AM) that would go on to feature many sports radio personalities such as Marv Albert and Howie Rose.
