Twitter has also been a significant social media platform for K-pop stars to get connections and promotions. The viral song "Gangnam Style" gained popularity from mentions by prominent Twitter users. Bang Si Hyuk, the producer of BTS, partially attributed the fast growth of their fanbase to social media such as Twitter. On November 13, 2017, BTS became the first South Korean act to reach 10 million followers on Twitter. In 2017, BTS was the most tweeted-about artist both in the United States and globally. Other K-pop groups, such as Seventeen and Monsta X, also appeared in the global top ten. Exo, a South Korean boyband, was the most followed celebrity to have entered Twitter in 2017. At the 2017, 2018, and 2019 Billboard Music Awards, BTS won the award for Top Social Media Artist based on Twitter voting by their fans. According to Sin Chang Seob, the CEO of Twitter Korea, the usage of Twitter by K-pop artists has increased Twitter's popularity among South Koreans.
