Let me know when you find this mythical buyer for the radio stations. Radio is even more of a declining asset than television and the only people buying up stations are Godcasters like K-Love or Relevant Radio. Let's be real: Nexstar, Gray, Tegna, Sinclair and Sinclair know they can't find a third party for the radio stations and they aren't going to bother with Cox.
NewsNation is cheap and they hire cheap talent. They make good money on retransmission revenue from cable companies and don't have to pay for acquired programming like movies. That's the only reason why it's around.
I hope you are aware that younger demos and more and more of the 25–54 "money demo" are abandoning linear television for streaming. The audience for local television is getting smaller and grayer and the industry is on an unsustainable course with pushing endless local news to markets that can't support it. Nexstar, Gray, Tegna, Sinclair and Scripps are all destined to be too big to fail.
As for Apollo, they are only guilty of being 10 years too late buying Cox and four years too late trying to sell it.
