Michael Riley, a former head of ABC Family, is the new president of Los Angeles-based KCETLink, the independent public media station and satellite TV channel. Riley succeeds Al Jerome, the KCET executive who led what had been PBS’s flagship station in Los Angeles through its acrimonious 2011 split from PBS. He spearheaded the station’s subsequent merger with noncommercial satellite broadcaster Link TV in October 2012. Dick Cook, board chair for KCETLink Media Group, cited Riley’s “strong track record in brand-defining content creation, strategic partnerships, acquisitions and digital leadership — both domestically and across international markets” in Monday’s announcement. Riley began in the job immediately.
