"Breaking news" used to be relevant in that it was news that "broke into" existing programming. It didn't necessarily make people's lives better but at least it tended to cover matters of high national interest like Presidential assassinations or disasters or wars. But now that everything is breaking news all the time everywhere, the term no longer means anything other than being a synonym for "current news," which isn't even really impressive anymore.
My life would not have been impacted in the least knowing about the Trump assassination attempt a few hours later (or even the next day), rather than minutes after it happened.
The MSM has enough problems these days with journalistic integrity and practices. I don't think the teeming mobs on Twitter are an improvement, though.
