The K-pop Hot 100 was a music singles chart in South Korea, launched by Billboard in conjunction with Billboard Korea (빌보드코리아) on August 25, 2011. It is the second Asian Billboard chart after the Japan Hot 100. The chart used the same multimetric methodology as the US Hot 100 and rankings were compiled based on Hanteo Chart data, streaming and download data from Naver VIBE, and domestic radio and television music playback data. Updates were published on Billboard Korea's website every Tuesday, and appeared on billboard.com the following day.
