When you watch TV programs such as British Got Talent, the TV hosts sometimes say:
''Next up is the talented singer from...'' (performers number or sequencing method kind of thing)
Whereas, when you play Youtube, then there a window on the uppermost right corner link indicating ''up next''.
What is the difference between up next and next up?
I've been seeing this for a long time, and I'm not sure why they have to change this every now then, or maybe there's a real difference between both. I googled it but none of the results answered my question.
