During the beginning of the 21st century, K-pop idols began receiving success elsewhere in Asia: in 2002, Baby Vox's single "Coincidence" became popular in many Asian countries after it was released and promoted during the World Cup in South Korea. BoA became the first K-pop singer to reach No. 1 on the Japanese Oricon music chart and shortly afterwards, Rain had a sold-out concert to an audience of 40,000 fans in Beijing. In 2003, Baby Vox topped the Chinese music charts with their Chinese single "I'm Still Loving You" from their third album "Devotion", the first idol group to do so, creating a huge fanbase in China. They also charted in various music charts in Thailand. TVXQ marked the rise of K-pop boy bands in Japan. In 2008, their single "Purple Line" made TVXQ the first foreign boy band and second Korean artist after BoA to top the Oricon music chart.
