The station signed on in 1991 as WCZQ. It has been through multiple formats, including rhythmic and
country. On February 1, 2024, Neuhoff Media sold radio stations in
Danville and
Decatur to Champaign Multimedia Group for $2 million. The sale closed in May; on June 1, the station would assume new
call sign WKIO, which moved from
107.9 FM, and on June 18, the station dropped the previous Neuhoff format, an
urban contemporary format branded as "Hot 105.5", and assumed the branding and part of the format of 107.9 (shifting from the
classic hits format it had on 107.9 to a
classic rock format with the move to 105.5), with the stations simulcasting temporarily ahead of a move on the latter station. While Neuhoff ran WCZQ from Decatur, Champaign Multimedia Group operates WKIO alongside its existing properties in Champaign. ==References==
