The sale of ABC Radio and its 22 owned and operated stations, including San Francisco’s KGO-AM 810 and KSFO 560, to Citadel Broadcasting will become final on June 12, according to a press release from the current owner, Disney. Disney plans to keep its 50 Radio Disney stations nationwide including 5,000-watt KMKY 1310. The FCC approved the $2.7 billion deal in March. KGO-AM and KSFO are expected to remain at the ABC Broadcast Center at 900 Front St. but pay rent to Disney.
