Jeff Clarke, president and CEO of San Francisco’s public broadcaster KQED since 2002, is retiring, the San Francisco Chronicle says.

Clarke—who will stay in the job for one year, or until transition to a replacement is completed—vastly expanded the reach of KQED in Northern California. KQED’s TV station is one of the most-watched public stations nationwide, and its radio station also pulls in a large listenership.
