Veteran KNBR sports talker Bruce Macgowan has been let go by the station’s new management in what’s described as a cost-cutting move. “I thought the new owners would wait a little while before making cuts,” Macgowan told the Chron. Susquehanna Broadcasting sold KNBR, KFOG and KSAN to Cumulus Media last fall. Also shown the door were sports sales manager Bob Sargent and business operations director Valerie Blackburn.
