John Seabrook marks the rise of K-Pop:

K-pop is an East-West mash-up. The performers are mostly Korean, and their mesmerizing synchronized dance moves, accompanied by a complex telegraphy of winks and hand gestures, have an Asian flavor, but the music sounds Western: hip-hop verses, Euro-pop choruses, rapping, and dubstep breaks. K-pop has become a fixture of pop charts not only in Korea but throughout Asia, including Japan—the world’s second-biggest music market, after the U.S.—and Taiwan, Singapore, the Philippines, Hong Kong, Thailand, Vietnam, and Malaysia. South Korea, a country of less than fifty million, somehow figured out how to make pop hits for more than a billion and a half other Asians, contributing two billion dollars a year to Korea’s economy, according to the BBC. K-pop concerts in Hong Kong and on mainland China are already lucrative, and no country is better positioned to sell recorded music in China, a potentially enormous market, should its endemic piracy be stamped out. Yet, despite K-pop’s prominence in Asia, until recently few in the United States had heard of it.
