Dan Seeman helped birth now-dominant radio juggernaut KFAN, then moved to Hubbard radio to manage a powerhouse signal (KS95) and two afterthoughts, the innovative female-driven FM 107 and legacy flagship ESPN 1500. FM107 is now a national success story, while 1500 is being retooled for a post-broadcast era. What that means is anybody’s guess, but Seeman and acting program director Phil Mackey need to figure out, in a digital era, how to create platform-agnostic content in a sports-glutted marketplace. It’s an ambitious agenda where success is hardly assured, but Seeman has been exposed to enough compelling content over the years to know what people want. Now the question is how they want it.
