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.

He and Gunnar Weidenfels detail the blockbuster unbundling of WBD: Decision "reflects our belief that each company will go further and faster apart than they can together."

Warner Bros. Discovery shareholders just rejected CEO David Zaslav's pay package. Wall Street thinks a split-up of the company may be next.
