But going back to my original post, it would not be much of an exaggeration to say that KFI didn't kill KABC, Rush Limbaugh himself did. It was when Rush came on in 1989 that KFI's ratings really took off. Today Rush is doing just fine, Michael Jackson and the Old KABC guard, not so much. KABC itself is a shell of its former self. Rush slew them all.
If you look at the books from the mid-90's, you can see that it was Rush plus Dr Laura that built mid-days. But their "magnet" capabilities allowed mornings and afternoons to take off.
My point is that it was the combo of Rush and Laura that made KFI build so strongly, not just Rush.
