Local news tends to be much more actionable as member of that locality at least in my experience. Things like when the burglary season starts, local/regional investment opportunities (e.g. wind farms), gatherings, events, road blocks due to construction.
Not American and dunno about CNBC, but national news seems more for economic decision makers, politicians. Not saying nobody else should have access to that sort of thing, but it's cognitively too hard to follow for me alongside everything else.
It's a difficult delivery/targeting problem. Everything's happening all the time. Right (truthful and complete) information for the right person (role, intention, interest?) at the right time/occasion (entertainment, time-sensitive, deliberate research?). And to be clear: I do not necessarily mean algorithmic targetting or recommendation. E.g. the (hobbyist) historian certainly wouldn't want to be swayed this way.
Incidentally sifting through news archives is something LLMs might be quite good at, e.g. for consolidation, comparison, lookup. However they mustn't kill their sources doing that. There's no replacement for primary sources (except AGI yadda yadda)
