KMCA meaning in Community ?

The Gaon Music Chart (Korean: 가온 차트) tabulates the relative weekly popularity of songs or albums in South Korea. It is produced by the Korea Music Content Association and sponsored by South Korea's Ministry of Culture, Sports and Tourism, with an aim to create a national chart for South 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 February 23, 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, the song "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.

In February 2011, it published information on both online and offline album sales of 2010, including a detailed breakdown of online chart data and was the first time since 2008 that offline album sales were released, since the Music Industry Association of Korea had stopped compiling data.

The word gaon means middle or center in Korean, and it was chosen to represent fairness and reliability.
