You might have heard the public service announcements running on KGO-AM 810 or KSFO 560, where production manager Michael Amatori reads a list of shareholders who are buying the radio stations? Seven Bay Area radio stations are changing hands in two separate transactions. As reported on this web page Feb. 6, Disney is spinning off its ABC radio stations across the country, including KGO-AM and KSFO, into a new company, 52% of which will be owned by Disney shareholders and the rest by Citadel Broadcasting shareholders. No management or format changes have been announced, but the on-air announcements about the license transfer are making people scratch their heads. In addition, as reported by Bay Area Radio Digest, the licenses of five stations owned by Susquehanna Broadcasting are being transferred to Cumulus Media Partners, an investment group that includes three private capital firms that were interested in buying Knight Ridder (Thomas H. Lee Partners, The Blackstone Group and Bain Capital). The five stations are KNBR-AM 680 and KTCT-AM 1050, “The Bone” KSAN 107.7, KFOG 104.5 and KFOG’s South Bay repeater, KFFG-FM 97.7.
