The current KBRU license is the third to operate on 94.7 in Oklahoma City.
KOCY-FM
The first was KOCY-FM, which was the first FM station to broadcast in the state, opening on September 16, 1946. Initially broadcasting on 98.5 MHz, KOCY-FM was co-owned with KOCY. KOCY-FM quickly increased its effective radiated power, to 3,000 watts in January 1947; it changed frequencies to 94.7 in mid-1947. A year later, KOCY-FM activated a new transmitter site and increased its power to 70,000 watts, claiming "the tallest exclusive FM tower in the world". KOCY-FM was additionally used to feed eight AM stations in a statewide network that began operations in September. KOCY-FM ceased operations in 1950. Its tower was acquired by station KOMA for use in broadcasting television.
KEFM/KMWC
It would be another eight years before a new 94.7 station operated; on August 17, 1958, Carl E. Williams opened KEFM, offering a "fine music" format. The fine music outlet was hit with staff turmoil in 1960 when it moved to a more upbeat music policy during the daytime hours; former station manager Earl Thomas claimed no involvement with the change. 1963 saw an even larger change; the station moved to Midwest City and adopted new KMWC call letters to reflect its home. KMWC, along with KJEM-AM-FM, carried daily radio broadcasts from Tinker Air Force Base. However, Williams made an ill-advised move; he leased the station for six months in 1964 to Marlin Joe Pershall without Federal Communications Commission approval. In March 1965, the FCC fined Williams $1,000. Later that year, the station was deleted, and the FCC set aside the fine that December.
History
KEBC
The Electronic Broadcasting Company applied on October 9, 1965, to build a new FM radio station on 94.7 in Oklahoma City. The FCC approved its application for a construction permit on August 17, 1966, and KEBC—named for the owner—signed on in May 1967. The station was a country music outlet, broadcasting from studios at 3920 SE 104th Street on the city's southeast side; in 1970, the studios were moved to 830 SW 31st Street. In 1971, Ralph Tyler and Harold McEwen bought a majority share in KEBC, and a new tower facility followed in 1973. KEBC established itself as a force in the market; it pulled double-digit ratings in each year between 1979 and 1982, fighting with KKNG and KTOK for the top spot in Oklahoma City. However, KEBC gained a formidable competitor on May 27, 1982, when KXXY-FM flipped to country. The more aggressive KXXY-FM edged ahead of KEBC in 1983 and would widen its lead to eight ratings points by the end of the decade. While KXXY-FM surged, KEBC was sold several times. Van Wagner Broadcasting, which only owned two outlets in Michigan, bought the station from Ralph Tyler for $4 million in 1986. Two years later, Van Wagner sold KEBC to Independence Broadcasting for $3.9 million. Independence would see a return on its investment when Clear Channel Communications, forerunner to iHeartMedia, acquired KEBC for $7.5 million in 1993.
Alternative, soft rock, and alternative again
After 28 years in the country format, KEBC relaunched on July 3, 1996 as an alternative rock station known as "95X", adopting the call letters KNRX. It was the market's first station in the format. However, less than 18 months later, another change came. On November 7, 1997, after repeating the song "A Change Would Do You Good" by Sheryl Crow for an hour, KNRX became soft adult contemporary KQSR, seeking to target the 35–44 audience and citing the duplication of alternative music on stations in other formats in Oklahoma City. The station returned to alternative on July 8, 2002 and became KHBZ-FM "The Buzz", stunting beforehand with a buzzing noise played over the soft rock songs and notifying listeners that their "technicians were working to get 'the Buzz' out". On January 11, 2008, at 5 p.m., the station began stunting with all-Metallica, relaunching the following Monday with an active rock format. Despite a format emphasizing active rock and some classic rock titles, KHBZ-FM was still placed on the alternative rock panel by Radio & Records/Nielsen BDS. By the spring of 2009, KHBZ had adopted Clear Channel's syndicated Premium Choice active rock format, becoming musically identical outside of morning drive to sister stationsKIOC in Beaumont, Texas and WHRL in Albany, New York.
The Brew
On December 29, 2009, The Buzz gave way to KBRU "The Brew", a mainly 1980s-based rock outlet billed as "Classic Rock's Next Generation". Since adopting the Brew moniker, KBRU has shifted between rock formats on several occasions. In 2012, the station began playing more recent titles, bringing it closer to the music mix on KHBZ-FM before the format flip; later in the year, the station added more classic rock titles, eventually moving fully to classic rock as a competitor to KQOB. Since 2015, when the station moved back to mainstream rock, KBRU has oscillated between classic and mainstream rock formats.
Translators
KBRU's only translator carries its HD2 subchannel, a regional Mexican format known as El Patrón.
