There lies the problem, Urban Adult Contemporary equals nearly all black and very limited audience, thus harder to survive in highly competitive, multicultural markets like NYC. Whereas, a full-service, urban contemporary can pull a wider audience (age and racial demographic) and have a better ability to thrive all the while serving that same community. The point nowadays is to serve the community and survive the tremulousness PPM environment.
Irrespective of the true meaning of "tremulousness" you need to take a Black perspective here: saying that Urban Contemporary "serves the same community" as "Urban AC" is like saying that a conventional AC serves the same "community" as a CHR. There are, and the cume duplication shows it, many Black listeners who never sample urban offerings... because that format does not serve a great many adult African Americans.
When we look at a variety of other markets that have Urban ACs we find that they often do as well or sometimes better in adult demos than urban stations.
