KRTH
KRTH (101.1 FM, "K-Earth 101") is a commercial radio station that is licensed to Los Angeles, California, United States and serves the Greater Los Angeles area. The station is owned by Audacy, Inc. and broadcasts a classic hits format. KRTH's studios are located on Wilshire Boulevard in the Miracle Mile district of Los Angeles. The station's signal covers an extremely large area of Southern California due in part to its antenna location on Mt. Wilson. It can be heard as far south as San Diego, as far east as Palm Springs, as far west as Santa Barbara, and as far north as Barstow. KRTH is the flagship station for the nationally syndicated program Rewind with Gary Bryan.
KRTH broadcasts in the HD Radio (hybrid) format.
In May 1940, the Federal Communications Commission (FCC) authorized an FM band effective January 1, 1941, operating on 40 channels spanning 42–50 MHz. (This was later changed to 88–106 MHz, and still later to 88–108 MHz, which increased the number of channels to 100.) On October 31, 1940, the first fifteen construction permits for commercial FM stations were issued, including one to Don Lee Broadcasting System for a station in Los Angeles at 44.5 MHz, which was issued the call sign K45LA. K45LA signed on August 11, 1941, as the first FM station in Los Angeles, broadcasting from a tower atop Mount Lee; it is the oldest continuously operating FM station in California. Effective November 1, 1943, the FCC modified its policy for commercial FM station call letters, and the call sign was changed to KHJ-FM, after its sister AM station KHJ. In 1946, as part of a transfer of stations to the new FM band, KHJ-FM was assigned to 99.7 MHz. In 1947, KHJ-FM was reassigned to its current broadcast frequency of 101.1 FM, eventually relocating its transmitter to Mount Wilson.
In 1965, when KHJ adopted its "Boss Radio" top-40 format, that station was simulcast on KHJ-FM. From 1968 to 1970, KHJ-FM aired Drake-Chenault's "Hit Parade" format, an automated mix of older songs and current hits. In 1971, the station carried another Drake-Chenault top 40 format, "Solid Gold Rock And Roll".
On October 16, 1972, KHJ-FM switched to what was then called a "gold" format, featuring older hit songs from the past. At the time, this "oldies" format featuring songs from 1953 to 1963 was a novel idea since most stations played current music with only a few older songs mixed in. The only local competition in this format was KWOW (1600 AM), a mostly automated station in nearby Pomona. With the switch in format came a new moniker: "K-Earth", named after Earth Day which had debuted to much fanfare two years before. New matching call letters KRTH accompanied the change. The "K-Earth 101" jingle was also introduced at this time; it directly echoed the sound and notes of the jingle from KHJ, the station where many of these "gold" songs had originally been played. (KHJ was still on the air at this point, but was playing current top 40 songs.)
In the late 1970s, under program director Bob Hamilton, KRTH added current hits to its oldies playlist—essentially an adult contemporary format. Though current music was played to varying degrees through the early 1980s, K-Earth's format remained focused on the past.
In 1985, KRTH solidified its oldies format, adopting the motto "Classic Rock and Roll". K-Earth began promoting its "Good Time Oldies" image with frequent TV ads featuring Beach Boys music, classic cars, palm trees, and the ever-present K-Earth jingle. The songs featured were from 1955 to 1978, with the focus largely on the 1960s. Doo-wop, early rock, Motown, girl groups, Elvis Presley, and the Beatles were the mainstays of the station's music mix. Throughout the 1980s, K-Earth would feature huge weekend specialties, including #1 music over the Labor Day weekend. Every L.A. #1 song would be played in chronological order (utilizing the older KHJ Boss 30, KFWB Fab Forty, and other local charts) from 1955 through 1985. The weekend before would feature the "Runners Up of Classic Rock and Roll Weekend", consisting of #2 songs. The "Firecracker 300" was played over the Fourth of July weekend. Other specials included a Memorial Day weekend "A to Z", the "Super Sixties Weekend", and the "Souvenirs of the Seventies Weekend". In February 1986, KHJ adopted the KRTH call letters; this necessitated the FM station adjusting its call sign to KRTH-FM. In 1988, RKO General sold KRTH-AM-FM to Beasley Broadcasting due to the scandals involving KHJ-TV which forced the former company out of broadcasting.
Oldies were a ratings success for KRTH-FM and similar stations across the United States and Canada. In March 1989, another Los Angeles FM oldies station emerged at 93.1 FM under the call sign KODJ, later KCBS-FM, as a direct competitor to KRTH-FM. KODJ/KCBS-FM played oldies from 1955 to 1972 with a heavy focus on pre-1964 oldies. KRTH-FM, which reverted to the KRTH call sign in May 1990, continued acknowledging the mid- and late 1970s and continued playing moderate amounts of pre-1964 material until 1991, when management eliminated the 1980s music and most post-1972 songs. The two stations went head-to-head for a few years, with K-Earth consistently getting higher ratings and emerging as the winner. In an attempt to distinguish itself from K-Earth and regain the oldies audience, KODJ changed its call letters to KCBS-FM and, in early 1993, began playing mostly pre-1965 oldies. KCBS-FM successfully switched to a classic rock format in late 1993 called "Arrow 93", but later flipped to adult hits as "Jack FM". KRTH, by then, focused on the 1964–1969 period with moderate amounts of pre-1964 and 1970s songs each hour. The station remained a competitor with Pasadena's AM oldies station KRLA until 1998, when that station switched formats. KRTH was sold to Infinity Radio in 1994.
