Claim: Larry King, who began his broadcast career in Denver, leaving it in 1981 to join KSL-TV, an NBC-affiliated television station licensed to Salt Lake City, Utah, United States, in Salt Lake City as weekend sports anchor before returning in 1982 to join KOA-TV / KCNC-TV (KOA became KCNC in 1983) to host Denver Broncos pre-game shows and weekend sports, spent two years as ESPN TV's frontline College Football announcer including bowl games, and also called Men and Woman's NCAA College Basketball and the Arena Football League post-season.
Evidence: King began as a local Florida journalist and radio interviewer in the 1950s and 1960s and gained prominence beginning in 1978 as host of The Larry King Show, an all-night nationwide call-in radio program heard on the Mutual Broadcasting System. 
A CBS staff announcer, whom King met by chance, suggested he go to Florida which was a growing media market with openings for inexperienced broadcasters. When one of the station's announcers abruptly quit, King was put on the air. His first broadcast was on May 1, 1957, working as the disc jockey from 9 a.m. to noon.
