Four years ago, David Zaslav clinched a debt-heavy deal to merge cable mainstay Discovery Inc. — which he’d run since 2006 — with what was then called WarnerMedia. The story he told investors was that the two entities’ diverse array of media assets “are better and more valuable together.” He doesn’t believe that anymore.

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 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.
