Rumors about this have been swirling for a while. The Puck News folks have been discussing pros and cons of Zaz going after Paramount Global or its parent company, National Amusements ( with corporate finance issues at stake way above my ability to even pretend to decode), and the original Axios story on this says that it still could go either way.
Of course WBD itself will likely eventually be breaking itself into pieces and selling off to someone like Comcast. So this could be CBS and Showtime merging with CNN and HBO and then with NBC (that is the merger that will have real antitrust hurdles).
The Feds will have to sort through the competition issues, but really consolidation in the television+streaming business at least (not so sure about film production) is inevitable and probably desirable. I will be happy to only subscribe to a combined Max+Paramount,rather than two, hopefully with at least some net price break.
