The owner of CNN and HBO Max, Warner Bros Discovery, says it will split into two companies by the middle of next year. The US media giant plans to separate its studio and streaming business away from its more traditional cable television networks.

Warner Bros. Discovery is splitting into two separate publicly traded companies – one oriented around the HBO Max streaming service and Warner Bros. studio, and the other around CNN and other television networks.

Warner Bros. Discovery said in December that it was implementing a restructuring plan in which Warner Bros. Discovery would become the parent company for two operating divisions, Global Linear Networks and Streaming & Studios. That was seen as a preview of the separation announced Monday.
