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.

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.

He points out that the AT&T deal that formed Warner Bros. Discovery in the first place helped set the template Zaslav and Wiedenfels are following into the future with Streaming & Studios and Global Networks.
