Rickey Floyd "Rick" Carroll (September 15, 1946 – July 10, 1989) was an American program director (PD) for influential radio station KROQ-FM in Los Angeles, California, United States, where he introduced the "ROQ of the Eighties" format.
Noted for his ability to pick breakout hits, Carroll guided songs to prominence via the "Hot Clock," a pie chart prescribing the music to be played during each portion of a disc jockey's air shift.
His system also included a "Jock's Choice" at the end of each hour of programming, during which a DJ could play any song of his or her own choosing.
The Jock's Choice became a vehicle for new artists such as Depeche Mode and Juluka to break into KROQ-FM's regular rotation.
Starting in 1983, Carroll consulted other radio stations where he implemented the Rock of the Eighties format, including 91X (San Diego, CA), KYYX (Seattle, WA), KPOP Roseville / (Sacramento, CA), WAAF (Boston, MA), WIFI (Philadelphia, PA), KQAK (San Francisco, CA), WRQC (Cleveland, OH) and WYDD (Pittsburgh, PA) among many others.
