There are the venerable institutions of PBS and NPR in the US, broadcasting on television and radio respectively, as well as increasingly online through video and podcasts.
ProPublica is probably the best known of the recent arrivals, providing investigative journalism at a national level.
I'd submitted a couple of items on Chicago's public radio station, WBEZ, acquiring one of the city's two remaining daily print papers, the Sun Times.

The other, the Tribune, was acquired by the vampire-capital firm Alden Capital somewhat over a year ago and has been emitting coronal mass ejections of reporters, columnists, and staff, since, though many curiously remain on the paper's masthead...).
WBEZ didn't pay for the acquisition, it was paid to take over the paper. Which might tell you something of the market for print news media presently.
Another notable example is the Baltimore Banner, which officially launched two weeks ago on June 14. It's another non-profit, is looking to expand to 70 journalists. It is online-only.

But both the Sun Times and the Banner are big-city papers. They're not papers reaching into small towns and rural areas, in which the news desert truly exists.
I see two possible paths forward. One is for news-as-public-good, in which jouranlism is publicly (and preferably locally) supported. Another is a return to the partisan press of the past, notably the 19th and early 20th centuries. Given the dominance of right-wing talk radio, Fox, OANN, Breitbart, and similar organisations, it seems at least one political party is already largely there.
