For much of its early history, the station had music formats and was aimed towards a black audience.

From 1956 to 1991, the station had call sign KDAY and had top 40, rock, and R&B formats through the early 1980s. In 1983, KDAY became the first station in Los Angeles to playhip hop music; as a result, KDAY became the most popular station among black listeners in the area.
KDAY went through multiple ownership and format changes in the 1990s, beginning with a purchase byFred Sands in 1990. A year later, KDAY changed its call sign to KBLA and its format to business news. The business format lasted just one year, as KBLA changed to a Korean format afterwards. Keymarket Communications purchased KBLA in 1993; subsequent mergers of its parent company landed KBLA under the ownership ofRiver City Broadcasting in 1995 andSinclair Broadcast Group in 1996. KBLA was sold in 1998 to Radio Unica, which added KBLA to its national Spanish radio network.Multicultural Broadcasting bought KBLA in 2003 and converted KBLA to a Spanish Christian format.Tavis Smiley bought KBLA in 2020 and launched a progressive talk format on the station.

Originally, the station at 1580 kHz made its first broadcast July 30, 1947 as KOWL, a 5,000-watt,daytime-only station licensed toSanta Monica. It was owned and operated by Arthur H. Croghan, formerly commercial manager forWJBK inDetroit.[2] The opening day celebration for KOWL on August 10 included such notable figures as Los Angeles MayorFletcher Bowron, Santa Monica Mayor Mark T. Gates, country singerGene Autry, and actressMarilyn Monroe.[3] However, KOWL broadcast for only six and a half hours that day due to technicianswalking out of the job due to a dispute overunionization.[4]
KOWL's studios were located at the Ambassador Hotel in Santa Monica.[2] It had amiddle of the road music format.[3] Croghan excluded what he called "commercial religion, disc jockeys, murder mysteries, double spotting, over-commercialism, and...talk exceeding five minutes except in rare instances."[2] In 1948, Autry became a minority owner of KOWL, and the station began orienting its music and programming towards black listeners.[5] Autry sold back his stake in KOWL to Croghan for $80,000 in October 1949.[6]
On May 1, 1956, KOWL changed itscall sign to KDAY, a nod to its daytime-only broadcast hours.[7][8][9] KDAY changed its format to mainstream pop music, as shown by surveys from the time.[10]
In January 1957, Radio California purchased KDAY andCorona TV stationKCOA for $650,000.[11] KDAY's studios and business offices moved from Santa Monica toHollywood in April 1957.[12] KDAY began carrying newscasts from theLos Angeles Herald-Express newsroom in July 1957.[13]
From 1958 to 1961,Earl McDaniel was a DJ at KDAY.[14] where he was soon joined byArt Laboe.Alan Freed worked for KDAY for about a year beginning in 1960 after losing his job atWABC in New York City over thepayola scandal.[15][16]
In April 1962, Rollins Broadcasting (later Continental Broadcasting of California) purchased KDAY for $850,000 in addition to a $150,000non-compete clause.[17][18] Rollins changed the music format to R&B.[10]
Beginning July 22, 1966, KDAY changed its format toadult standards where DJs played songs by telephone requests; Mexican stationXERB inTijuana picked up KDAY's old R&B format around a week later.[19][20]
In the late 1960s, KDAY received approval from theFederal Communications Commission (FCC) to operate at night. The studio and transmitter site were moved to a new facility on North Alvarado Street north of downtown Los Angeles. In early 1969, KDAY changed totop 40 and became a member of theABC Radio Network,[17] then toalbum-oriented rock (AOR) in 1971. During the Top 40 and AOR eras, the station was programmed by Bob Wilson, who would later launch the media magazineRadio & Records. KDAY reverted to soul/R&B in January 1974.
In 1978, KDAY had the highest ratings among the four black radio stations in Los Angeles, ahead ofKACE,KJLH, andKKTT. For aBillboard profile that year, KDAY program director J.J. Johnson said the station had an "uptempo approach" to music; the station's slogan at the time was "We got the funk!"[21]

Facing tougher competition fromFM stations likeKJLH, KDAY became the first Los Angeles radio station to playhip hop music in 1983. Under new program director anddisc jockey Gregory "Greg The Mack Attack" MacMillan, hired fromKMJQ in Houston, added hip hop to the station's playlist to appeal to mostly youngBlack andLatino listeners.DJ Dr. Dre andDJ Yella Boy became the first mixer DJs at the station.[22] By September 1983, KDAY upgraded its sound toAM stereo.[23]Dan Charnas described that move as "laughable" and "sounding liketwo tiny AM radios playing side by side."[24]

In 1987,Compton-based gangsta rap groupN.W.A made its radio debut on KDAY. In the first ratings period under MacMillan's leadership, KDAY's ratings beat another Los Angeles black AM station,KGFJ, and "began to enjoy a second life as the only rap-friendly station in town and, frankly, in the entire country."[25]
KDAY raised awareness about the growing problem ofgang violence in Los Angeles.Lee Marshall, known on-air as "King News", gave news and commentaries relevant to the African-American and Hispanic communities, often warning about the troubles caused by gangs.[26] After violence in the stands forced the cancellation of aRun-DMC concert at theLong Beach Arena for the group'sRaising Hell tour,[27] KDAY organized a "Day of Peace" on October 9, 1986.[28] In a two-hour special, KDAY featured Run-DMC, singerBarry White, and boxerPaul Gonzales appealing to rival gangs to stop feuding and opened phone lines for callers to describe gangs' impact in their communities.[29] There were no murders or incidents of gang violence that day. Within two weeks, theBloods andCrips, the two largest gangs in Los Angeles, signed a peace treaty.[28]

The business format lasted just one year; KBLA changed to a Korean format branded "Radio Korea" in January 1992.[37] KBLA also broadcast sevenLos Angeles Dodgers games a year in Korean; whenChan Ho Park joined the team in 1994, KBLA began broadcasting games where he pitched.[38] KBLA expanded its Dodgers coverage to 60 games in 1998.[39]
Nearly a year after the1992 riots on May 1, 1993, KBLA andKJLH broadcastBridging the Gap, a special joint call-in program aiming to improve relations between the black and Korean communities.[40]
