How popular is K-pop around the world?

Context: Modern K-pop "idol" culture began in the 1990s, as K-pop idol music grew into a subculture that amassed enormous fandoms of teenagers and young adults. After a slump in early idol music, from 2003, TVXQ and BoA started a new generation of K-pop idols that broke the music genre into the neighboring Japanese market and continue to popularize K-pop internationally today. With the advent of online social networking services and South Korean TV shows, the current spread of K-pop and South Korean entertainment, known as the Korean Wave, is seen not only in East Asia and Southeast Asia, but also in Pakistan, Bangladesh, India, Latin America, North Africa, Southern Africa and East Africa, the Middle East and throughout the Western world, gaining an international audience.

Answer: K-pop is a popular music genre that has a fan following across the whole world. It spread to worldwide fandom with the advent and proliferation of online social networking services.
