The K-pop kings join Justin Bieber in ruling the list for triple-digit weeks.

BTS reaches the century mark atop Billboard's Social 50 chart, as the superstar K-pop group leads for a 100th week on the list dated Nov. 17.

BTS becomes the first group, and second artist overall, after Justin Bieber, to log a triple-digit stay at the top since the chart began in December 2010.

The Social 50 is powered by data tracked by music analytics company Next Big Sound and ranks the most popular artists on Facebook, Twitter, Instagram, YouTube, Wikipedia and Tumblr. The chart's methodology blends weekly additions of friends/fans/followers with artist page views and engagement. The chart's latest tracking week ended Nov. 8.

BTS' 100th week at No. 1 on the Social 50 is the second-best showing among all acts, trailing only Bieber's 163 non-consecutive weeks in charge. The two powerhouses are far and away the leaders on that front; Taylor Swift ranks third on the leaderboard, with 28 frames on top.

Since BTS debuted on the Social 50 chart dated Oct. 29, 2016, the group has not held the No. 1 rank for only nine of 109 chart weeks and has yet to fall below the runner-up spot. The seven-member act's outstanding social statistics fueled them to back-to-back victories as top social artist at the 2017 and 2018 Billboard Music Awards, ending Bieber's six-year winning streak.

The ARMY, BTS' highly engaged fan base, has helped the group set successive Billboard chart records for the K-pop genre. After BTS' 2017 set Love Yourself: Her became the first top 10 album on the Billboard 200 by a K-pop act, the group quickly topped that feat with the genre's first two No. 1s: Love Yourself: Tear in June and Love Yourself: Answer in September.

On the Billboard Hot 100, BTS broke through with the first top 40 hit by a K-pop group -- "Mic Drop," featuring Desiigner, which hit No. 28 in December 2017 -- and subsequently the first top 10 ("Fake Love") this past June. The group nearly returned to the tier in September with the Nicki Minaj-assisted "Idol," which reached No. 11.
