KCKC (102.1 FM) is an adult hits radio station based in Kansas City, Missouri, that operates with an ERP of 100 kW.

Also that year, WDAF-FM flipped to oldies, the first time an FM station in Kansas City had attempted at the format.

KYYS became the most successful AOR station in Kansas City, hitting #1 in the ratings in 1979 when acts like Bad Company, Styx, REO Speedwagon, Bob Seger, KISS and Journey were popular, along with legendary personality Max Floyd's anti-disco speeches under the name "The Rock and Roll Army."

This began the end of KY's long dominance in the ratings, as KQRC took away many listeners with new hard and modern rock that KYYS generally ignored.

When KY finally started playing acts such as Pearl Jam and Red Hot Chili Peppers, it was too late, and their ratings never recovered.

By 1997, KYYS leaned very heavily on new music, playing as much of it as they could from artists like Dave Matthews Band, The Wallflowers, Sheryl Crow, and Collective Soul.

(In fact, the official goodbye came a week after the format change, when KYYS staff members held a midday interview simulcast on KQRC and KCFX, which were then owned by the same company).

In 2005, KSRC changed to a more upbeat image, dropping most soft-sounding music, with John Tesh's syndicated "Intelligence For Your Life" added to the evening schedule in the later part of the year.

While popular for many years, both KUDL and KCKC began to decline in the Arbitron ratings after the introduction of the Portable People Meter in early 2009.

In addition, most adult contemporary stations across the country were declining in ratings during this time period, due to challenges while attempting to attract a younger audience.

During the station's annual Christmas music run on December 22, 2010, KCKC began promoting "a new sound coming" on January 3, 2011.

[17][18][19] Initially, the format had a precise gold lean to it, mostly concentrating on rock music from the 1980s, and a wide library, with less of a focus on personalities.

"Alice" competed with Entercom's modern rock KRBZ, Cumulus Media's classic rocker KCFX, and non-commercial AAA-formatted KTBG.

On January 27, 2014, Wilks registered the domain "KC1021.com", possibly signaling another format change or altering for the second time in three years.

On February 4, at 6 p.m., after playing Semisonic's "Closing Time", KCKC began stunting with a countdown to 3 p.m. the following afternoon, when the station flipped back to adult contemporary, branded as "KC 102.1".

On that day, at 9 a.m., after playing "All I Want for Christmas is You" by Mariah Carey, KCKC flipped to adult hits, branded as "102.1 Bob FM"; the move mirrors a national network of the format, but more relevantly mirrors a similarly operated station, WRRK in Pittsburgh, operated by Steel City.
