 One of WJLB's most popular programs during its early years was the "Interracial Goodwill Hour", a jazz and R&B show hosted by later Cleveland radio legend Bill Randle.By the 1960s, WJLB had competition for Detroit's black audience in the form of 1440 AM WCHB and later 107.5 FM WGPR, and WJLB evolved into a chiefly R&B/soul music station, using the slogan "Tiger Radio" for a time in the late 1960s.Perhaps WJLB's most well-known personality in the 1960s and 1970s was Martha Jean "The Queen" Steinberg, one of the first successful female air personalities in Detroit, best known for her trademark line, "I betcha!"
