I'd imagine it's the things that still kinda make it as headlines today, but don't get much coverage anymore because everyone is used to it by now.
"By the way, this weekend's mass shootings led to 10 deaths and 29 injuries total, a little more than last week. Parents, remember to bundle up your kids this fall semester with the latest BulletBlocker Youth Jacket, 10% off if you order today! Now back to the news you actually wanted to hear about: the former U.S. President allegedly commits even more crimes..."
Yeah, but you have to consider that "Italian democracy overthrown by former journalist" and "bank sprayed with tommy gun" was recent news at that point. All that shit would shock people in the 60's, but in the 20's the main revelation would be the affordability of bulletproof clothing.
