I've just been assuming it's all gotten way, way worse over the last 20 years or so, too. One of the main things keeping it even slightly in check was local newspapers and TV stations with actual reporters.
Those are all gone, either shuttered or snapped up by huge companies that fired most of the staff and are milking them for the last money they can provide, or using them to distribute propaganda (e.g. Sinclair), and nobody's ever going to (be able to) do a proper accounting of how much the resulting waste and corrosion of public trust has cut into the actual overall cost/benefit of this whole "Internet" thing.
