The Wonder Girls became the first Korean singers to enter the top 100 of the main Billboard chart.

The Wonder Girls, one of South Korea's top girl groups, has been active in the United States and recently became the first Korean singers to enter the top 100 of the main Billboard chart.

``Nobody,'' which was unveiled in the United States in June, ranked 76th on the October Billboard Hot 100. The song was written by Park Jin-young.

The Billboard Hot 100 is one of the two most important charts in the U.S., the world's largest music market, listing the top 100 songs regardless of genre, and is frequently used as the standard measure for ranking songs in the U.S.

The Wonder Girls, the five-member band, made its debut in the States in the summer, releasing an album in English and joining the Jonas Brothers on a concert tour.

The group signed a management contract with the Jonas Group and Hollywood's Creative Artists Agency (CAA) was chosen as the band's agency in the U.S.

Meanwhile, the Wonder Girls made a surprise return Thursday to have a rest at home. The group consists of Sun, Yenny, Mimi, Sohee and Yubin.
