People often say, “Well, I only know what I read in the newspapers,” or “I read it in the newspapers.”
No they didn’t. Almost nobody reads actual newspapers.
Now it’s just an expression like, “It’s the greatest thing since sliced bread.”
Sliced bread was invented in 1912 and in common use by 1928. We’ve had WAY better things since sliced bread.
But I guess saying, “I read it in the newspaper” sounds much better than, “I read it on my phone while on the throne.”
