History Of K-earth 101

tuning into k-earth 101 in car


KRTH is the oldest continuously operating FM station in California and became the first FM station in LA on 11 August 1941. Originally K45LA it switched its sign to KHJ-FM in 1943. By 1947 the station was reallocated to its current broadcast frequency of 101.1 FM.


In 1972, there was a change to what was then called a “gold” format, featuring older hit songs from the past. The change in format meant a new moniker, ‘K-earth’ which was named after Earth Day and the letters became KRTH. The jingle for ‘K-earth 101’ was presented at the same time and directly resembled the sound/notes of the KHJ jingle, many of the ‘gold’ songs had been played there originally but KHJ was still on air playing top 40 songs. Oldies was a ratings triumph for KRTH-FM.


K-earth was the home to The Real Don Steele and Robert W. Morgan from 1992 to 1997, who were colleagues at KHJ during the 1960s Boss Radio era. In 1996 KRTH changed hands with Infinity being bought by Westinghouse Broadcasting (at the time owned by CBS) making KRTH and KCBS-FM sister stations. K-earth remained playing oldies, altering it to the end of the decade with older songs from before 1964 (British Invasion) being dropped. The station began to emphasise music from the late 60s, in particular Motown.


In the early 2000s, K-Earth began adding 1970s songs into the playlist. Particularly disco as its target demographics were ageing and ratings declining. Artists including Stevie Wonder, Elton John, ABBA, the Bee Gees were combined with 1960s artists such as The Supremes and the Beatles. The playlist was rotated more frequently even though it was still repetitive. In 2007 the process was taken further with songs from the 80s being added to the mix from artists including Phil Collins and Hall & Oates. K-Earth improved its ratings significantly by late 2007 and was again ranked in the top 10 stations in LA. More notably from an advertising standpoint, the station attracted a younger target audience.  The station reached their first #1 overall in the Arbitron 12+ Ratings in November 2009. The station had never reached a #1 overall in its 37 years broadcasting as K-Earth.


K-earth added songs from the mid-to-late 80s in 2010 as another change they added adult contemporary Christmas music around the same time during the holiday season. Music featured performers such as Mannheim Steamroller and Air Supply. The songs were aired three times per hour and were designed to encourage listeners away from contemporary competitor KOST. From 12:00 p.m. on Christmas Eve to 12:00 p.m. on Christmas Day, KRTH switches to an all-Christmas music format.

As of early 2016, KRTH began including songs from the 1990s into their playlist. On February 2, 2017, CBS Radio announced it would merge with Entercom.  By 2018, KRTH doesn’t play 1960’s or early 1970’s music. The playlist shifted to concentrating on hits from the 70s through the early 2000s, with a major focus on the 80s although the playlist is being reduced so there isn’t an overlap with sister station KCBS-FM, which airs an adult hits format.

As well as Rewind with Gary Bryan, KRTH also broadcasts America’s Greatest Hits with Scott Shannon and the 80s and 90s editions of Backtrax USA with Kid Kelly on the weekends. Bryan, Kelly and Shannon were previous DJs at Z100 in New York City.

Being on an established radio station can be the making of an artist. K-earth 101 is a top station amongst the key 25-54-year-old demographic of listeners. As an artist getting on air can be challenging and very competitive. However, there are some easy steps you can take in order to succeed. As an artist, you need to be familiar with the importance of being played on the radio to reach your chosen demographic.

The more times your music is heard and played on the radio the better it can be for your career.  An understanding of promotion is necessary to set yourself apart from the competition.  The best way to get your song on the radio is to contact the radio stations that are appropriate for whichever stage you are in career-wise. If you’re just starting to break into radio, focus on the non-commercial stations as they are the most likely to play independent up and coming artists. Community radio stations are often relaxed and a good place to start.

Create a realistic, clearly managed radio campaign and listen as your success climbs on the airwaves and in the meantime see what other artists have made it by listening to K-earth 101!
