K-pop (an abbreviation of Korean pop; Korean: 가요kayo) is a musical genre originating in South Korea that is characterized by a wide variety of audiovisual elements. Although it comprises all genres of "popular music" within South Korea, the term is more often used in a narrower sense to describe a modern form of South Korean pop music covering mostly dance-pop, pop ballad, electronic, rock, hip-hop, R&B, etc.
In 1992, modern K-pop was ushered in with the formation of Seo Taiji & Boys, whose successful experimentation with different music styles had sparked a paradigm shift in the music industry of South Korea. As a result, the integration of foreign musical elements has now become a common practice in the K-pop industry. By tapping into social networking services and the video sharing platform YouTube, the K-pop industry's ability to secure a sizeable overseas audience has facilitated a noticeable rise in the global proliferation of the genre.
