The station began broadcasting in 1949, and held the call sign WJIZ.[1] The station was owned by South Shore Broadcasting Company.[1] In 1954, the station's call sign was changed to WJOB-FM, and the station simulcast the programming of its sister station WJOB 1230.[1][4] In 1959, the station was sold to Percy Crawford for $119,000.[5][1] The station's call sign was changed to WYCA, standing for "Young People's Church of the Air", and the station began airing a Christian format.[6][1]
The station switched to an urban contemporary format on March 26, 2001, in an attempt to go head to head with the longtime urban radio leader in Chicago, WGCI-FM.[7] The station's call sign was briefly changed to WVJM in April 2001, before being changed to WPWX on May 1, 2001.[2] WPWX currently is the Chicago home to The Rickey Smiley Morning Show, and at one time carried both the Doug Banks Morning Show and The Tom Joyner Morning Show.[8][9][10]
