The Warner Bros. Discovery split became pretty much a foregone conclusion, last December, after C.E.O. David Zaslav announced that he was restructuring his company’s assets into two organizations. One of the new companies will consolidate WBD’s streaming and studios divisions (which represent the path forward), while the other, Global Networks, will bundle the linear channels—which, as you know, are moneymaking but irreversibly decaying assets. Comcast C.E.O. Brian Roberts made a similar move a couple months ago, spinning out Comcast’s own lackluster cable offerings—and handing Zaz a roadmap for his own breakup.
