KDAY-FM: First HipHop Oldies Station?

According to this article, Atlanta's L.A.'s KDAY is pushing itself as the first Hip-Hop Oldies radio station. I'm thinking this is probably true since "radio" would exclude dedicated satellite and internet channels, which we know have been around for a minute. I can't help but think that the emergence of a radio station serving this niche might not have come to fruition if it wasn't for Satellite radio's (and the internet's) ability to test the waters and prove their is a market.
