Stations don't "bill themselves" as anything in the real-time monitoring services... those services use an evaluation of each station, its demos and its playlist to determine how they will classify stations. Similarly, the format names we see online on the sites that list ratings are given by the site proprietory.
My point is that KBXX can, quite successfully, target African Americans. KMEL can't, as there is not the population base of Blackes to sustain it. KBXX is mostly Black targeted, while KMEL is mostly Hispanic targeted, but with a coalition of other and Black.
The Box is one of the most successful Urbans there is, relative to population base in the market. The are, in fact, the industry leader that showed how to recover from the initial impact of PPM, fix up the programming, and return to the same dominant position they had in the diary. Few stations have done that as well as KBXX.
The station is #1 in 12+, 18-34, 18-49 and 25-54. Not only is that a huge recovery from the earliest PPM test days in Houston, it is the mark of a station with good usage and acceptance. The fact that it was not even in the top 10 for a while shows that its target knows what it wants and does not listen when it is not good.
Even with KBXX at a high level, there is no guarantee that any new competitor would be able to shave more than a few points off
of them initially... and that would put them way outside the Top 10. That also means losing all the existing revenue and starting over at zere, and losing money for as much as a year as they get back on buys.
And if a new station only goes after the fringe of KBXX, as a CHUrban might, they have to create a coalition big enough to justify the initial revenue loss by giving a big payback in the second year and beyond. In today's economy, that is rather risky and usually only seen where a station is actually at or near unprofitability.
