A creation of SM Entertainment; the huge Korean artist management company that has also produced top artists like Girls' Generation and Super Junior, TVXQ! is arguably the biggest boy band in Asia. The group debuted in 2004 with "Hug" and quickly made it to the top of several Asian charts. Despite running a 2009 rift that saw three of the original members drop out due to conflicts with the management company (they went on to form the popular group JYJ), the remaining two members --Yunho and Changmin-- launched their album "Tone" in Japan. Never ones to be shy, the group's name (pronounced "Dong Bang Shin Ki") is the acronym for a Korean phrase that translates to "Rising Gods Of The East." No wonder they made it into the Guinness Book of World Records for having the largest official fan club, (close to two million fans worldwide).
