If they can afford it.
We already have that situation now. Everything is going behind a paywall. Especially investigative journalism.
It will be up to the journalists themselves to market what they do to reach their audience. Because the big companies won't do it for them.
They might have to become like Ken Burns, who raises his own money to pay for his movies that air on PBS.
I don't hold out hope for PBS member stations to be doing that type of journalism at the local level, either.
Once again, don't depend on companies or stations to raise money for journalists. The journalists have to raise their own money and bring their produced and sponsored work to the station. The media is that: A medium. Not an investment banker. That's mostly how PBS works.
Journalists have to be motivated by their own internal need to tell the story and help people, not by a salary with benefits.
