On July 4, 1958, a few months before companion station WKBW-TV (channel 7) was launched, WKBW radio abandoned its adult approach and was converted into a personality-driven full service Top 40 music radio station, featuring foreground personalities, a tight playlist of current hits and an aggressive local news department, which it continued to program with great success for over 20 years. It was one of the first stations to present traffic reports in cooperation with police and state and local authorities. Churchill sold WKBW-AM-TV to Capital Cities Broadcasting in 1961, earning a handsome return on his original investment of 35 years earlier.
