Baseball has become a big hit on satellite radio, where you can get live broadcasts of every major league game. “Satellite radio was initially conceived in part so music aficionados could skip between dozens of commercial-free stations playing classic rock, hip-hop and assorted other tunes as well as talk shows. But when XM included 16 channels devoted to baseball games this season, the company learned that its customers were as interested in hearing Vin Scully and Bob Uecker as Kid Rock and Eminem. The reaction was incredibly emotional and incredibly personal.”
