Before 1970, the most popular radio stations in the U.S were run by white people. But that all changed when Percy Sutton helped to form Inner City Broadcasting with the mission of putting black programming in the hands of black people. Together he and his son Pierre—and later Pierre’s daughter, Keisha—built a radio empire. But it was about more than just entertaining listeners; together they changed the culture and radically influenced how radio stations and record labels treated black artists. Alex talks with Pierre and Keisha about the unlikely rise—and heartbreaking fall—of their family business.
