cnbc.com
Paramount Skydance, whose CEO David Ellison is friendly with the Trump administration, wanted to buy WBD outright, making several bids for its full portfolio.
First reaction coming in now from the Trump administration to the blockbuster Netflix deal to acquire Warner Brothers: a senior administration official told me moments ago their initial view of this deal is “heavy skepticism.” That portends a lengthy and difficult DOJ antitrust

“AI is likely playing a role in the layoffs because companies that are investing more in the technology need to cut costs elsewhere, but there is little to suggest the latest cuts are directly related to AI replacing a person’s job, labor experts and economists said.”
Behind the wave of white-collar layoffs: Old-school cost cutting, tariffs and, yes, AI
