The Korean wave or Korea fever (a.k.a. Koreanophile) refers to the significantly increased popularity of South Korean culture around the world since the 21st century, especially among the Net Generation. It is also referred to as Hallyu (Hangul: 한류; Hanja: 韓流; RR: Hallyu), from the Korean pronunciation. The term was coined in China in mid-1999 by Beijing journalists surprised by the fast growing popularity of South Koreans and South Korean goods in China.
