Just three years after the iconic Warner Bros. film studio and television business was acquired for $43 billion by Discovery, the two companies are being split in two again. On one side will reside Warner Bros.

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.

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.
