KMJ (AM)

KMJ first signed on in March 1922, and was originally owned by the San Joaquin Light and Power Corporation. It was later acquired by the McClatchy Newspaper Company in 1925, which also published the daily newspaper The Fresno Bee.[2] KMJ is the 38th oldest licensed, and continuously operated radio station in the United States. It remains one of only a few dozen stations to keep their original three-letter call sign from their founding.

When the station first began broadcasting, it was licensed as an "E & M" station, and shared those frequencies with every other E & M station in existence at the time. KMJ operated on a number of other frequencies between 1925 and 1932. Some of the frequencies used included 820 and 1350 kilocycles. In 1931, KMJ operated on 1210 kHz, with a power of 100 watts (cf. White's Radio Log, Spring / Summer 1931). In 1935, KMJ was on the current frequency of 580 kHz, with a power of 500 watts (cf. White's Radio Log, Nov. 1935).

McClatchy was intent on improving the signal, and competed with KTAB in Oakland (now KSFO San Francisco) for the 580 frequency, which was being made available by the newly created Federal Communications Commission (FCC). Until 1936, and the arrival of KARM, KMJ was the only radio station in Fresno.

Eventually, McClatchy was awarded the new channel, and KMJ moved to 580 kHz, effective July 22, 1932, with an increase in power from 100 watts to 500 watts with unlimited time.[3] Later, power was boosted to 1,000 watts, using a non-directional antenna from a building rooftop in Downtown Fresno.

The station was an affiliate of the Don Lee Network, and also carried CBS Radio Network broadcasts until 1936, when KMJ switched its affiliation to the NBC Red Network. It remained an NBC affiliate until NBC ceased hourly newscasts in the 1990s. KMJ then joined ABC. When CBS was acquired by the Westinghouse Electric Corporation (later be renamed CBS Corporation), CBS Radio acquired KMJ from American Radio Systems in 1998. It then began carrying CBS News at the beginning of most hours.

"Modern" studios were constructed as an addition to the Fresno Bee Building on Van Ness Avenue. The studios were subsequently used by Valley Public Radio, and later, McClatchy donated the entire building to the Fresno Metropolitan Museum. The radio studio addition was demolished in 2007, as part of a renovation of the main building.

At the outset of World War II, the Department of War selected KMJ as the primary medium for alerting Central California residents. It is still used for this purpose today as a primary entry point for the Emergency Alert System.

From 1925 until 1987, KMJ was owned by McClatchy, which also owned KFBK in Sacramento, KBEE in Modesto, KERN in Bakersfield, and KKOH (formerly KOH) in Reno. McClatchy Newspapers also owned three daily newspapers in Fresno, Sacramento, and Modesto.

In 1949, KMJ gained a sister station with KMJ-FM 97.9 MHz going on the air. At first, it simulcast 580 KMJ. It later played classical music and then switched to an automated Top 40 sound in the 1970s. Today it is KMGV. In 1953, a television station was added, KMJ-TV on Channel 24. Because KMJ Radio was a longtime NBC affiliate, Channel 24 carried NBC Television Network programming. The TV station was sold off in 1981 to become KSEE.

In November 2006, KMJ and its sister stations KFPT AM 790, KWYE FM 101.1, KSKS FM 93.7, KFJK FM 105.9, KOQO FM 101.9 and KMGV FM 97.9 were sold by CBS Radio to Peak Broadcasting for $90 million.

In March 2009, as more listeners were tuning to FM radio, Peak Broadcasting decided to put KMJ on the FM band. It replaced the KFJK Jack FM format on 105.9 FM, with Talk programming as KMJ-FM. At first, only some programs were shared by both KMJ-AM and FM. But now, all programming is simulcast.

In the fall of 2012, Premiere Radio Networks, owned by Clear Channel Radio, exercised a termination clause and ended its relationship with KMJ-AM-FM. As of January 1, 2013, all Premiere syndicated shows, including Rush Limbaugh and Sean Hannity, were moved to Clear Channel-controlled stations in the greater Fresno area. KMJ-AM-FM used the opportunity to go with an all live and local line-up of shows from 5 A.M. until 6 P.M., Monday through Friday.

On August 30, 2013, a deal was announced in which Townsquare Media would purchase Peak Broadcasting, and then immediately swap Peak's Fresno stations, including KMJ, to Cumulus Media in exchange for Cumulus' stations in Dubuque, Iowa and Poughkeepsie, New York. The deal was part of Cumulus' acquisition of Dial Global. Peak, Townsquare, and Dial Global are all controlled by Oaktree Capital Management.[4][5]

The sale to Cumulus was completed on November 14, 2013.[6] Under Cumulus ownership, KMJ-AM-FM became affiliates of co-owned Westwood One News.
