At that time Russia was allied to France, Spain and Portugal were largely under French thumb, and only the United Kingdom of Great Britain and Ireland were against the First French Empire of Napoleon.
(Not too many people know this , but at that time Russia had 24 million and France had 25 million (plus 15 million controlled by various entities ruled by Napoleon's relatives), since the explosion of Russian population didn't take place until in 1861 Czar Alexander II emancipated the serfs.)
KPop in 2010 was even worse. I don't know how to make maps, but in 2010, KPop would have ruled most of the map, including most of the islands of Great Britain and Ireland, with Davichi (owned by Kwangsoo) owning what would be Northern Ireland and IU owning what would be Scotland.
Basically the only reason there were other genres in Korean pop after 2010 was solely because of the efforts of one person - Lee JIeun.
Korean ballad, Hip Hop, R&B, Trot, you-name-it, after 2010 owned their existence to IU.
KPop had destroyed every other genre. Every single genre. by Dec 2010. Its domination was even stronger than now.
Because IU had defeated Sistar, Kara and Big Bang in a quick succession at the end of 2010 with Good Day, suddenly the vulnerability of KPop became apparent and other genres began to attack KPop, culminating with IU's winning of the Golden Disk with the folk-ballad Through the Night, which is the only nonKPop song to win a Grand Prize since the Kpop era began in 2007 (unless we count Lim Youngwoong in Melon 2022; it is likely that he won't be welcomed in this year's MMA unless its organizers want to rename it the Melon Trot Awards. When people like Busker Busker won, MMA was not considered to be a serious award.)
For all practical purposes, IU held the complete domination of Korean music industry by KPop for 13 long years.
But now the dam is caving down since the power of Kpop is so great that all other genres, who never really became popular outside of Korea, cannot compete any more.
IU herself stood up against BTS, became its biggest rival and rose to the #9 position of the world ranking (most awarded singer of year) solely because of her Korean efforts, but now the pandemic is over and concerts are being held everywhere, the power of Kpop cannot be stopped by anyone and all other genres now can't compete.
With the effective surrender of the very person who extended the life of nonKpop genres for 13 years to NewJeans, it seems K-hiphop, K-R&B. K-you name it are all going to be buried in the sands of time.
How history will record IU is an interesting prospect. Would she be remembered as a quixotic fool who resisted KPop's domination by 13 years and retarded history, or remembered as a hero who wanted to maintain the music variety? That will be a question to be answered many moons away from now, but for now KPop is finally conquered, completely, by KPop.
