WBZ sure is one of those enduring radio brands.
And, yes, Boston does have a long News/Talk tradition.
Even waaay-back-when 'BZ still played-the-hits, their wee-hours Talk blocks were already a fixture.
In my travels, I still meet Baby Boomer-age DX-ers who tell Larry Glick stories.
He had lots of fans in the Midwest.
RE "Does breaking news stop when it gets dark:"
As WBZ sister station WINS/NY has said for 40+ years, "the news watch never stops."
And 'BZ has set-the-expectation that, if-the-fit-hits-the-shan, they'll swing-into-action.
But lots of stations daypart day-in-day-out PROGRAMMING the way WBZ does.
Their daytime
news format plays to the big available weekday in-car
cume.
Evening
talk shows can be
AQH engines.
When I programmed WTOP/Washington in the 80s, the station was 1500AM, so we played the signal's strengths-and-weaknesses:
By day, we were All-News during the day.
Evenings: play-by-play (Orioles, before baseball came back to DC; and the NHL Capitals; and NBA then-Bullets/now-Wizards);
Overnights: Larry King, who was a Washington local then.
Now, WTOP is a multi-FM simulcast, and somewhat-the-other-way-around: They're all-news-all-the-time, for an increasingly-mobile around-the-clock community there, and their coverage geography accommodates the bigger signal footprint. And they ALMOST go-Talk middays, with interview segments that don't interrupt traffic and service elements.
And stations elsewhere also daypart in-the-fashion WBZ does.
Which opens-the-door for WRKO-type talkers, who -- while WBZ-type stations spin the news wheel -- offer daytime Talk.
