No, it is aimed at 25-64 male sports fans. You are putting a racial twist on what is a simple marketing reality.
The fact is that, for example, different groups may have different interests in sports. A huge percentage of Hispanics don't follow ythe sports that American all sports stations carry. And all-sports has not been successful to any great extent in Latin America.
The Hispanic percentage is now over 50% in the sales demos. Asians and Asian Americans are not well measured in ratings due to language (no recruiting of PPM materials in any Asian language). The Black population is so small that it's not viable to target them (that is why The Wave, while called Urban A/C, is principally targeted at the 94% of the market that is not Black.
Generally, sports talk does pretty well with Blacks, particularly if the station has a local team on with play by play. Sports talk does not do well with Hispanics, even in Latin America.
You are looking at ratings as a sign of success. It's about billings. And sports stations have access to sports marketing dollars that are not radio-specific.
Please don't make so much of everything you post in some manner about race. Radio has always been a less racially affected industry. Going back 67 years, my first radio job was as the token minority at an R&B station in Cleveland where, despite being only 250 watts high on the dial, it outbilled several general market stations because businesses wanted to reach Black people.
