History
WNWC
The station began broadcasting on March 10, 1960, holding the call sign WNWC ("North West Communities").[1][5][6] In July 1961, the station was purchased by Bob Atcher and Thomas Hogan.[5][7] WNWC would air a wide variety of non-rock music.[5] It aired four hours of country music a day before increasing it to 12 hours a day in November 1963.[8] In 1965, Lester Vihon purchased the station for $110,000.[5] By 1966, it was airing hard rock evenings.[9] The station was off the air temporarily in June 1966, after a tornado toppled its tower.[9] In early 1968, the station was sold to auto dealer Walter Mack for $150,000.[5][10]
WEXI
In April 1968, the station's call sign was changed to WEXI, and was branded "Stereo Excitement".[2][11] WEXI aired easy listening music during the day and a progressive rock format overnight.[12][13] Shortly thereafter, it adopted a top 40 format.[14][5] In November 1970, the station adopted a beautiful music format, with the slogan "Spreading Clean Air over Chicagoland".[14][5][15]
WWMM
In autumn 1972, the station was sold to Community Broadcasters for $230,000, and its call sign was changed to WWMM.[16][2] WWMM aired contemporary middle of the road music, along with some talk programs.[5][17][18] Among the shows on WWMM in this period was "Love in the Afternoon", a sex talk program hosted by Jonathan Kingsley.[18] By 1976, the station had adopted a jazz format.[5][19] In 1976, the station was sold to Northwest Community Broadcasting for $500,000.[20][2] By 1977, WWMM was airing a MOR-adult contemporary format, with the slogan "Radio for the Great Northwest".[21][22][23]
WTCO
In spring of 1981, the station was sold to Radio Communications Group and its call sign was changed to WTCO.[2][3][5] WTCO aired a country music format.[5][24] In 1982, the station was sold to Darrell Peters Productions for $550,000.[25][26]
WSEX
Darrell Peters Productions applied to change the station's call sign to WSEX on September 26, 1982, but the application was rejected.[27] An application to reconsider was submitted, and the call sign change was approved on January 24, 1983.[27][28][29][3] WSEX aired an adult contemporary format called "Love Songs & More".[30] In January 1986, the station adopted a "Top 10" format, playing songs that had reached the top 10 within the past five years.[31][32][33]
WCBR-FM
The station became "Chicago's Bear", and its call sign was changed to WCBR-FM on January 9, 1989.[3][34] WCBR-FM aired an adult album alternative format.[35][36][37] As the 90's progressed, it began to air brokered programming nights and weekends.[37] WCBR-FM also aired Chicago Wolves hockey.[37][38]
In 1998, the station was sold to Big City Radio for $17 million.[39] Many of the brokered programs that were on WCBR-FM moved to 94.3 WJKL in Elgin.[39] Purchased by Big City Radio at the same time was 92.7 WLRA in Kankakee.[40] When Big City Radio took control of the two stations, they stunted with a simulcast of their Los Angeles sister station 107.1 KLYY, which aired a modern rock format.[41] WLRA's call sign was changed to WBRO shortly thereafter.[42]
92 Kiss FM (WKIE-FM)
On November 14, 1998, at Noon, WCBR and WBRO launched their new official format, CHR as "92.7 Kiss FM", with the first song being "Kiss" by Prince.[43][44][45] This would be Chicago's first true CHR station in many years and proved to be quite successful, even with the two stations' weak signals.[43][38][44] In late December 1998, the station's call sign was changed to WKIE, while WBRO's call sign was changed to WKIF.[3][42] Big City Radio also purchased WDEK 92.5 in DeKalb, Illinois, which was airing a locally programmed CHR format at the time, and switched it to a simulcast of WKIE and WKIF in early 1999.[46] Not long after, the moniker was adjusted to "92 Kiss FM".[47]Melissa Forman hosted mornings on 92 Kiss FM, before moving to 93.9 WLIT-FM in 2001.[48][49]
Energy 92.7&5
On January 12, 2001, Clear Channel's WUBT changed formats from rhythmic oldies to CHR as WKSC-FM "Kiss 103.5".[50] At that time, Clear Channel filed suit against Big City Radio, alleging the "Kiss FM" branding used by WKIE and its simulcasts violated its national trademark.[50][51] However, Big City Radio had already planned on changing the formats of these stations.[51] On January 26, 2001, 92 Kiss-FM signed off, and the three stations adopted a dance hits format as "Energy 92.7&5".[51][52] The station's airstaff remained intact.[53][54] The new format was designed by 92 Kiss FM's program director, Chris Shebel, who has stated that the dance hits format is something he had dreamed of doing for a long time.[51]
In 2004, Spanish Broadcasting System sold WKIE, WKIF and WDEK to Newsweb Corporation for $28 million.[61][62] At 9 a.m. November 29, 2004, WKIE and WDEK began simulcasting with its new adult hits sister station 99.9 WRZA in Park Forest, Illinois, as "Nine FM", with the slogan "We Play Anything".[63][64] The first song on the Nine FM simulcast was "With or Without You" by U2.[63] Sky Daniels was the original program director for Nine FM.[63] When he left in 2005, he was replaced by Matt DuBiel.[64]
In 2006, Chris Chudzik began leasing air time for a dance music show called Dance Factory.[65][66] Initially airing overnight on Saturdays,[65] the program was expanded to seven nights a week on May 14, 2007.[66] Dance Factory has continued to air overnight on the station, even as its daytime format has changed.[67][68]
Chicago's Progressive Talk (WCPT-FM)
Newsweb Corporation dropped the Nine FM programming on all three signals on October 20, 2008, and replaced it with a simulcast of sister station WCPT from 5 a.m. until 9 p.m.[69][67] The Nine FM format moved to WKIF 92.7 in Kankakee.[70] On October 27, 2008, the station changed its callsign from WKIE to WCPT-FM, to go with the format.[3]
Polski FM (WCPY)
On June 2, 2014, WCPT-FM and 99.9 WCPQ broke away from the progressive talk simulcast and changed their daytime format to Polish, branded as "Polski FM".[68][71] WCPT-FM then swapped callsigns with 92.5 WCPY in DeKalb, which remained part of the progressive talk simulcast.[3][71] In 2018, 99.9 WCPQ was sold to Bible Broadcasting Network, and it adopted a Christian format as WYHI.[72] Polski FM was then briefly simulcast on 640 WMFN in the summer of 2018.[73] In October 2024, Newsweb agreed to cell WCPY to Mina Georgalas' Rhythm Enterprises LLC for $3 million; three of the company's members are associated with the "Polski FM" programming.[74]
