KDNX

KDNX (1200 AM) is a commercial radio station in Benton, Arkansas. It is owned by Beasley Broadcast Group and carries a sports format. KDNX's studios are located at Bennett Road in Downtown Benton, while its transmitter is located at Smith Pinnacle, between the border of Garland and Saline County.

As KEFL
On October 5, 1942, KEFL would begin broadcasting as the first major radio station in Benton, AR. The station was originally owned by the Benton School District, making it one of the few stations to be owned by a school district. It served as Benton's affiliate of the CBS Radio Network, and as such carried the majority of the network's programming. KEFL was also used by the school district to teach kids how to manage a radio station.

The station would receive an FM sister station, KEFL-FM on September 13, 1944 which was the first FM station in Benton and would also receive a TV sister station on July 18, 1953 known as KEFL-TV (which was an affiliate of the CBS television network) reflecting its AM sister's affiliation with the CBS Radio Network, KEFL-TV now serves as a viewer supported PBS affiliate.

In 1955, Harry Bitner would acquire KEFL-AM-FM-TV from the Benton School District, making them his 2nd major radio acquisition after he bought WOOD-AM-FM from ABC as a result of FCC rules at the time. In 1957, Bitner's assets were acquired by Time-Life for $16 million. Time-Life would retain the KEFL cluster until 1971 when it sold its broadcasting assets to McGraw-Hill. Around the exact same year, KEFL would drop CBS Radio programming, and would flip to a Top 40 format.

All-news radio
On April 15, 1976, McGraw-Hill would experiment with an all-news radio format on KEFL-AM, the first of its kind in Benton. The format proved successful and would become the official format of the station the following day. In 1978, McGraw-Hill would sell KEFL-AM-FM to LIN Broadcasting.

However, because FCC rules at the time prevented stations from the same market but different owners from having the same call-letters, KEFL-AM would change its call-letters to KINS, in tribute to WINS, a popular all-news station in New York.The call-letters however didn't last long as KINS would change its call-letters to KDNX on March 6, 1982, in tribute to another all-news station, this time KNX in Los Angeles. The KEFL-AM are now used by 580 AM in 2015.

In 1988, LIN Broadcasting would sell its Benton radio assets to Greater Media. Greater Media already had experience with the Arkansas market as it was the owner of KWW-AM-FM; as well as local Fox affiliate KWW-TV.

Sports radio
On July 8, 1992, KDNX would drop its all-news format and would flip to a sports format branded "1200 The Fan". The switch made it Greater Media's first sports radio station ever. KDNX would loss its longtime sister station KSSB (the former KEFL-FM) after it was sold to Evergreen Media (owner of KOLO-FM) in 1995, as a result of an FCC deal that year which no longer limited a radio company from owning 1 AM and FM per market.

On July 19, 2016, Beasley Media Group announced it would acquire Greater Media and its stations for $240 million. The FCC approved the sale on October 6, 2016, and the sale closed on November 1, 2016.
