K-pop hits the top of Billboard album chart

The South Korean boy band BTS is now the first K-pop group to reach No. 1 on the Billboard top 200. Love Yourself: Tear sold 135,000 units for the week ending May 24, as tallied by Nielsen Music.

The group, also known as the Bangtan Boys, has a devoted core of fans known as “the army,” and its appeal has been likened to Beatlemania in the 1960s. BTS is at the heart of a global trend known as “Hallyu,” or “Korean Wave.”
