Chris Licht is out after a year as chief executive at CNN, following a series of missteps and plunging ratings. David Zaslav, the CEO of CNN parent company Warner Bros. Discovery, announced the leadership change on CNN’s morning editorial call on Wednesday. Zaslav appointed a four-person leadership team to lead the network in the interim. Licht replaced Jeff Zucker as CNN’s chief executive last year, with a mandate to move the network more toward the political center.
