@futurebird look, the concept of nightly news used to be seen as a 'prestige' thing each network did to maintain visibility of their network and, to whatever actual extent this part of it was realized, to provide a public service.
Now, everything's got to sell the commercial space and bring in a return. The concept of noblesse oblige, if you will, has been lost. Everything is about engineering the audience.
A dozen years ago, maybe more, the stat was that for every one person with a comms or journalism degree working in public media, there were six working PR for companies, doing essentially the same job but with no accountability to truth or obligation to serve any form of greater good. That was back then. I shudder to think what it is now.
The message is the medium and the medium is the message these days and both are being aimed and calibrated by billion dollar enterprises and trillion dollar interests. There will be no return to a concept of an altruistic nightly news broadcast unless something wholly new arises to provide it.
