About K-POP from WIKI
K-pop (Korean: 가요, Gayo) (an abbreviation of Korean pop or Korean popular music) is a musical genre consisting of pop, dance, electropop, hip hop, rock, R&B, electronic music originating in South Korea.[6][7][8][9][10] In addition to music, K-pop has grown into a popular subculture among teenagers and young adults around the world, resulting in widespread interest in the fashion and style of Korean idol groups and singers.[11]
Through the presence of Facebook fan pages, availability on iTunes, Twitter profiles, and music videos on YouTube, the ability of K-pop to reach a previously inaccessible audience via the Internet is driving a change in the exposure and popularity of the genre.[12] South Korean popular culture is today serving as a major driver of youth culture all across the Pacific Rim, with special reference to China, Hong Kong, Japan, Philippines, Taiwan and Vietnam.
