The Chief Executive of CNN has stepped down after just 13 months on the job.
Chris Licht had been under pressure after a recent article about him in the Atlantic magazine, for which he provided an unusual level of access, raised questions about his leadership.
The news network has also seen falling ratings and was widely criticised for its handling of a town hall interview with former president Donald Trump.
Parent company Discovery said “things did not work out the way we had hoped”.
Mr Licht was appointed head of the channel last year, when Discovery merged with WarnerMedia, home to CNN, HBO and others.
Warner Bros Discovery boss David Zaslav said the company appreciated “Chris’s efforts and dedication.
“This job was never going to be easy, especially at a time of great disruption and transformation, and Chris poured his heart and soul into it,” he said announcing the change, which is effective immediately.
Mr Licht’s efforts to shake-up programming – including the launch of a new morning show – had stumbled.
His standing had been in question after a new chief operating officer, seen as close to the Discovery boss, was named earlier this month.
Before CNN, Mr Licht was an executive vice president of special programming at CBS and a showrunner for “The Late Show with Stephen Colbert”. He had also worked for CBS News and was a co-creator of MSNBC’s popular morning news show “Morning Joe”.
Mr Zaslav said the channel would be led by an interim group of leaders, while the company searched for a replacement.
