Although there are some exceptions, urban stations, in general, usually draw an audience between 30 and 60% white. That may or may not amount to a "sizable segment of the white population," but it's usually a sizable percentage of an urban station's audience. The more segmented urban-based formats, like urban AC, typically don't see the same diversity in audience.
If it gets enough of the audience within its main signal contour and they listen long enough, I suppose it could happen, but a 4 share out of the gate on signal like that would be TSL driven. I don't follow urban formats much, but I seem to remember your typical urban station is more cume driven than TSL driven. I tend to think it will probably debut in the higher 2-share range and burn into the upper 1's or lower 2's.
Your guess is as good as mine, though I don't think Katie & Company is going anywhere. So, she probably still has a job after this. Of course, all of us know why companies sack people with no notice and why some come into a new market and blow everyone out. You might or might not agree with what they do, but anyone who has been in this business long enough has encountered the reasons for those decisions. In general, you want to leave in as good of graces as you can when something like this happens. You're probably not going to work for Audacy for a really long time if you trash the company on-air when you're getting laid off.
In the case of WCCC, no one had any incentive NOT to rip EMF. EMF wasn't going to hire the WCCC jocks, and there were no other positions within the company. That might make other companies not want to hire those people, but, depending on the manner in which they do it, it's not going to matter as much.
