The long tail for the quiet storm listenners (or time zone segmentation)

I like Quiet Storm (QS) at WBLS very much. It is played 7:00pm NY, that means 8 am in Tokyo, but I am not really in the QS mood in the morning. When I am in the QS mode at night in Tokyo, they feature Steve Harvey which is fine but not so suitable to listen at night. Then I’ve found the WBLS sister station, KBLX of San Francisco, that plays QS all the time. It can, in effect, capture QS listeners online of any time zones across the globe. That is nice. That leads me to think the long tail curve for the quiet storm listeners something like:

At this point, I’d bet there are very few people listening online and their revenue depends purely on local advertising and no business model is yet established for online streaming program.  However, as more and more listeners will shift from offline radio to online and the competition will intensified, I hope the new form or style of online radio programs will emerge.
