The Gaon Music Chart tabulates the relative weekly popularity of songs or albums in South Korea. It is compiled by the Korea Music Content Industry Association and sponsored by South Korea's Ministry of Culture, Sports and Tourism, with an aim to create a national chart for Korea similar to the Billboard charts of the United States and the Oricon charts of Japan. It started tracking sales since the beginning of 2010. It was officially launched in February 2010 with a launching ceremony held on 23 February 2010 at the Westin Chosun hotel in Seoul. The launch also included a small awarding ceremony, which awarded girl group Girls' Generation with top artist of January and boy band Super Junior with best album of 2009. Meanwhile, Hit single "We Fell In Love", performed by Jo Kwon of 2AM and Ga-in of Brown Eyed Girls, took the title of best weekly mobile ringtone.
It originally started in 2009 for monthly top single sales, and has expanded to contain weekly single and album sales. The charts are released each Thursday.
