Yes, at least in my country (in Europe) I'm pretty sure that it's a recent trend to favor 100% single-fruit juices.
And I've seen the traditional juice fruite producers come up with increasingly comical/tragic ways to address it:
HUGE 100%, miniscule "natural ingredients" below it (so no motor oil at least xD )
HUGE name of a specific fruit, such specific fruit all over the box, big "100% fruit" and label saying 99.9999 apple, 0.0001 specificfruit powdered extract
If I mix 99% motor oil with 1% strawberry, that is a 100% pure fruit juice BLEND!
