Thompson has been signaling the move ever since taking over at CNN more than a year ago. The network's ratings have been tumbling, particularly after President Donald Trump's election.
“Our objective is a simple one: to shift CNN's gravity towards the platforms and products where the audience themselves are shifting,” Thompson said in a memo to CNN staff.
Thompson said the goal is to develop a way for digital subscribers to stream news programming on any of their devices. Corporate parent Warner Bros. Discovery is kicking in $70 million to implement the new plans, he said.
CNN is also planning to announce changes to its television lineup, expected to include a move of Wolf Blitzer to a morning show.
