WCTB originally signed on as an Adult contemporary music station in 1993. In the late 1990s the station went through several format changes, at times simulcasting the sports talk of WSKW and country (both classic and current country music) simulcasted on WCME (now WTQX).
In late 2003, when Clear Channel Broadcasting lost control of the station, WCTB began to stunt with Christmas music (as they had done every year from Thanksgiving to Christmas) In January 2004, the station began airing an eclectic mix of music, in alphabetical order, finally ending up with a classic hits format in April 2004.
With another ownership change in November 2004, WCTB changed to Christmas music again and after Christmas adopted a classic rock format that it kept until December 2010.
WCTB currently carries The True Oldies Channel with local programming originating in morning and afternoon drive. In January 2011 WSKW changed to a simulcast of WCTB, previous to the simulcast WSKW carried the oldies format as Legacy 1160. WSKW would change to ESPN Radio the next month, which it had carried previous to September 2009.
