>>19722535K-pop took off around the 2010s, believe in the west.
Believe around that pretty much most households had internet in the West and people getting familiar with their content and some marketing everyone know about K-Pop K-Drama.
Anime and J-RPGs only took with kids mostly, sadly their music didn't really take off so much.
I kind of like their music like rock, but it never took off in the west for whatever reason it's marketing or the people didn't like it so much.
