I remember hearing David Simon, creator of The Wire, predicting this (fall of local news enabling unchecked corruption). Here's an article on it from nearly 20 years ago:

> "Oh, to be a state or local official in America over the next 10 to 15 years, before somebody figures out the business model," says Simon, a former crime reporter for the Baltimore Sun. "To gambol freely across the wastelands of an American city, as a local politician! It's got to be one of the great dreams in the history of American corruption."

One of the seasons of The Wire is largely about a major newsroom (the Baltimore Sun, unsurprisingly) taking its first hard punch from the collapse of the news market and unchecked M&A activity, so I'm not surprised he commented on it elsewhere too. God, what a great show.

I'm not sure there is a viable business model for local investigative reporting waiting to be discovered, any more. At least not in the US, not in mid-sized or smaller markets. It's semi-functional in rich, dense cities. Might remain so for a while longer. It's just everywhere else that now has no watchdogs aside from the occasional, lazy, probably partisan look-see from state regulatory agencies, and maybe resource- and access-starved hobbyists if they're lucky. The pros are gone. A few still watching big national-scale stuff (bigger audience!) but all the smaller parts of the system have gone dark.

Corruption is not new- in fact looking at US history it appeared to be the norm. Tammany Hall, railroad barons, the Prohibition, Standard Oil. There were just a brief few decades after WW2 when it slipped into the background.
