Variety: Ten years after Sumner Redstone split CBS and Viacom into separate companies, Les Moonves doesn’t envision the two entities ever coming back together. In a keynote Q&A at the WSJD Live event in Laguna Beach, Calif., the CBS CEO cited the stark differences between the companies’ portfolios as the reason they will stay separate. “I do not see a scenario where the companies come back together, we’re on totally different paths,” said Moonves.
