A radio personality is a person who has an on-air position in radio broadcasting. A radio personality that hosts a radio show is also known as a radio host, and in India and Pakistan as a radio jockey. Radio personalities who introduced and played individual selections of recorded music were originally known as disc jockeys before the term evolved to describe a person who mixes a continuous flow of recorded music in real time. Broadcast radio personalities may include Talk radio hosts, AM/FM radio show hosts, and Satellite radio program hosts. Notable radio personalities include pop music radio hosts Martin Block, Alan Freed, Dick Clark, Wolfman Jack, and Casey Kasem, shock jock's such as Howard Stern, as well as sports talk hosts such as Mike Francesa and political talk hosts such as Rush Limbaugh.
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, radio personalities are expected to supplement their on-air work by posting information online, such as on a blog. 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 now accomplished 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.
Radio disc jockey history
In the past, the term "disc jockey" was exclusively used to describe on-air 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.
1900s to 1950s
In 1892, Emile Berliner began commercial production of his gramophone records, the first disc records to be offered to the public. The earliest broadcasts of recorded music were made by radio engineers and experimenters. On Christmas Eve 1906, American Reginald A. Fessenden broadcast both live and recorded music from Brant Rock, Massachusetts. In 1907, American inventor Lee DeForest broadcast a recording of the William Tell Overture from his laboratory in the Parker Building in New York City, claiming "Of course, there weren't many receivers in those days, but I was the first disc jockey".
Ray Newby, of Stockton, California claimed on a 1965 episode of CBS I've Got a Secret to be regularly playing records on a small transmitter while a student at Herrold College of Engineering and Wireless in San Jose, California in 1909.
By 1910, radio broadcasters had started to use "live" orchestras as well as prerecorded sound. In the early radio age, content typically included comedy, drama, news, music, and sports reporting. Most radio stations had an orchestra or band on the payroll. The Federal Communications Commission also clearly favored live music, providing accelerated license approval to stations promising not to use any recordings for their first three years on the air. Many noted recording artists tried to keep their recorded works off the air by having their records labeled as not being legal for airplay. It took a Federal court ruling in 1940 to establish that a recording artist had no legal right to control the use of a record after it was sold.
Elman B. Meyers started broadcasting a daily program in New York City in 1911 consisting mostly of recorded music. In 1914 his wife Sybil True broadcast records borrowed from a local music store. The first British DJ was Christopher Stone, who in 1927 convinced the BBC to let him broadcast a program consisting of American and American-influenced jazz records interspersed with his ad libbed introductions.
In 1935, American radio commentator Walter Winchell coined the term "disc jockey" (the combination of disc, referring to the disc records, and jockey, which is an operator of a machine) as a description of radio announcer Martin Block, the first announcer to become a star. While his audience was awaiting developments in the Lindbergh kidnapping, Block played records and created the illusion that he was broadcasting from a ballroom, with the nation’s top dance bands performing live. The show, which he called Make Believe Ballroom, was an instant hit.
Block was notable for his considerable influence on a records popularity. Block's program on station WNEW was highly successful, and Block was described as "the make-all, break-all of records. If he played something, it was a hit". Block later negotiated a multimillion-dollar contract with ABC for a syndicated nationwide radio show.
The earliest printed use of the term "disc jockey" appeared on August 13, 1941 when Variety published "... Gilbert is a disc jockey, who sings with his records." By the end of World War II, disc jockeys had established a reputation as "hitmakers", someone who's influence "could start an artist's career overnight". 
Disputes with the American Society of Composers, Authors, and Publishers (ASCAP) and the American Federation of Musicians (AFM) affected radio DJs during World War II. ASCAP and AFM cited the decline in demand for live appearances of musical artists due to the proliferation of radio disc jockeys playing recorded music. The disputes were settled in 1944.
1950s to present
The postwar period coincided with the rise of the radio disc jockey as a celebrity separate from the radio station, also known as a "radio personality". In the days before station-controlled playlists, the DJ often followed their personal tastes in music selection. DJs also played a role in exposing rock and roll artists to large, national audiences. While at WERE (1300 AM) in Cleveland, Ohio, DJ Bill Randle was one of the first to introduce Elvis Presley to radio audiences in the northeastern U.S.
Notable U.S. radio disc jockeys of the period include Alan Freed, Wolfman Jack, Casey Kasem, and their British counterparts such as the BBC's Brian Matthew and Alan Freeman, and in the '60s Radio London's John Peel, and Radio Caroline's Tony Blackburn. In the 1950s, Jimmy Savile became a radio DJ at Radio Luxembourg.
Freed is commonly referred to as the "father of rock and roll" due to his promotion of the music and his introduction of the phrase "rock and roll" on radio in the early 1950s. Freed also made a practice of presenting music by African-American artists rather than cover versions by white artists on his radio program. Freed's career ended when it was shown that he had accepted payola, a practice that was highly controversial at the time, resulting in his being fired from his job at WABC.
A number of actors and media personalities began their careers as traditional radio disc jockeys who played and introduced records, such as Hogan's Heroes star Bob Crane, talk show host Art Bell, American Idol host Ryan Seacrest, and Howard Stern.
Radio DJs often acted as commercial brokers for their program and actively solicited paying sponsors. They could also negotiate which sponsors would appear on their program. Many wrote and delivered the commercials themselves, talking the place of advertising agencies who formerly executed these responsibilities.
Radio disc jockey programs were often syndicated, at first with hourly musical programs with entertainers such as Dick Powell and Peggy Lee acting as radio DJs introducing music and providing continuity and commentary,  and later with radio personalities such as Casey Kasem who hosted the first nationally-syndicated Top 40 countdown show.
African American disc jockeys
African American radio DJs emerged in the late 1940s, mostly in cities with large black populations such as New York, Chicago, Los Angeles and Detroit. Prominent DJs included Al Benson on WGES in Chicago, who was the first popular disc jockey to play urban blues and use "black street slang" in his broadcasts, Jesse "Spider" Burke on KXLW in Saint Louis, James Early on WROX in Clarkesdale, and Ramon Bruce on WHAT in Philadelphia. Most major U.S. cities operated a full-time rhythm and blues radio station, and as African Americans traveled the country they would spread the word of their favorite radio personalities.
Nat D. Williams was the first African American disc jockey on WDIA in Memphis with his popular Tan Town Jamboree show. African American radio DJs found it necessary to organize in order to gain opportunities in the radio industry, and in the 1950s formed the National Jazz, Rhythm and Blues Disc Jockey Association. The group's name was later changed to the National Association of Radio and Television Announcers. In 1960, radio station managers formed the Negro Radio Association to foster and develop programming and talent in the radio broadcasting industry.
Especially during the 1950s, the sales success of any record depended to a large extent on its airplay by popular radio disc jockeys. The illegal practice of payment or other inducement by record companies for the radio broadcast of recordings on commercial radio in which the song is presented by a DJ as being part of the normal day's broadcast became known in the music industry as "payola". The first major United States Senate payola investigation occurred in 1959. Nationally renowned DJ Alan Freed, who was uncooperative in committee hearings, was fired as a result. DJ Dick Clark also testified before the committee, but survived, partially due to the fact that he had previously divested himself of ownership interest in all of his music-industry holdings.
After the initial investigation, radio DJs were stripped of the authority to make programming decisions, and payola became a misdemeanor offense. Programming decisions became the responsibility of station program directors. As a result, the process of persuading stations to play certain songs was simplified. Instead of reaching numerous DJs, record labels only had to connect with one station program director. Labels turned to independent promoters to circumvent allegations of payola.
From the late 50s to the late 1980s when the Top 40 music radio format was popular, audience measuring tools such as ratings diaries were used. However a combination of financial pressures and new technology such as voice tracking and the Portable People Meter (PPM) began to have negative effects on the role of radio DJs beginning in the late 1990s, prompting one radio program manager to comment, "There was a time when the “top 40” format was ruled by legends such as Casey Kasem, or Wolfman Jack, and others who were known for both playing the hits and talking to you. Now with PPMs, it is all about the music, commercials and the format." Such format changes as well as the rise of new music distribution models such as MP3 and online music stores led to the demise of radio DJs reputation as trend setters and "hit makers" who welded considerable influence over popular music.

Salary in the US
Radio personality salaries are influenced by years of experience and education. In 2013, the median salary of a radio personality in the US was $28,400.
- 1–4 years: $15,200-39,400,
- 5–9 years: $20,600-41,700,
- 10–19 years: $23,200-51,200,
- 20 or more years: $26,300-73,000.
A radio personality with a bachelor's degree had a salary range of $19,600-60,400.
The salary of a local radio personality will differ from a national radio personality. National personality pay can be in the millions because of the increased audience size and corporate sponsorship. For example, Rush Limbaugh was reportedly paid $40 million annually as part of the eight-year $400 million contract he signed with Clear Channel Communications.
Due to a radio personality's vocal training, opportunity to expand their career often exist. Over time a radio personality could be paid to do voice overs for commercials, television shows, and movies.
Universities offer classes in radio broadcasting and have a radio station, where a student obtain on-the-job training and course credit. Prospective radio personalities can also intern at radio stations for hands-on training from professionals. Training courses are also available online.
Some radio personalities do not have a formal education, but many hold degrees in audio engineering. Radio personality typically have a bachelor's in radio-television-film, mass communications, journalism, or English.
