Radio One is one of the best Urban operators. The are trying all news in Houston* and I hope they do well with it. But if you if you are going to expand into "new" markets common sense dictates you try to find markets with demo's that fit into your programming strengths, like:
Memphis, TN
Population: 1,104,200
PPM: Mon-Sun 6AM-Midnight | 43.9% Black | 7.3% Hispanic
New Orleans, LA
Population: 1,187,300
AQH: Mon-Sun 6AM-Midnight | 29.3% Black | 5.3% Hispanic
Jackson, MS
Population: 403,700
AQH: Mon-Sun 6AM-Midnight | 44.3% Black
*IMHO Radio One should develop some non urban stations. It would (when they get their financial house in order and it is reflected in the stock price) allow them to pick up some quality radio properties when Clear Channel finally has to sell the stations in the Aloha trust.
