Renick was unopposed as a South Florida anchor from 1949 when WTVJ aired programs from all networks via
kinescopes, until it became exclusively a
CBS affiliate in 1956. In that year, WCKT (now
WSVN), channel 7 began broadcasting in Miami as an NBC affiliate station, followed in the late 1950s by WPST-TV (now
WPLG-TV), channel 10, as
ABC's outlet in Miami (WTVJ was purchased by
NBC in 1987, but would not become an NBC station until 1989, when WSVN, the former NBC station, became a Fox affiliate, and WCIX assumed the CBS affiliation from WTVJ). Despite a strong attempt to challenge Renick and WTVJ over the years, he remained the dominant and number one rated news anchor for his entire 36-year run. In 1957, Renick broadcast the first of nearly 30 years of nightly editorials on his 6 pm newscast,
The Ralph Renick Report. Two years later, in 1959, he traveled to
Cuba for an exclusive interview with its new socialist revolutionary prime minister
Fidel Castro, and later that same year to the
Kremlin, to interview
Soviet Premier Nikita Khrushchev. In 1960, Renick named Dr.
Manolo Reyes, a former lawyer in
Cuba, and a pioneering Spanish-language broadcaster, to launch South Florida's first Spanish-language newscast on WTVJ. In 1967, he hired
Jane Chastain, the nation's first female sportscaster. A year later, in 1968, Renick made history again by hiring South Florida's first black reporter, C.T. Taylor. Renick pushed WTVJ to pioneer video tape and ENG (
Electronic News Gathering) in late 1974 and by November 1975 had the state's first truly mobile live truck up and running. Shortly after 3:00 pm on November 30, 1975, Renick
broke into regular programming to report an attempted assassination on
Ronald Reagan, in town for a speech at the
Miami Airport Ramada Inn. Because WTVJ's live capability was in place, Renick was able to throw to reporter Bob Mayer for the station's first live mobile field report (See link below). Renick, then a widower with six children, served on the board of directors of the
Associated Press from October 1977 to May 1981. ==Retirement==
