[2] Updates were published on Billboard Korea's website every Tuesday, and appeared on billboard.com the following day.
[2] Silvio Pietroluongo, Billboard's Director of Charts, called the launch "a milestone event", as it would "provide the Korean music market with what we believe is Korea's most accurate and relevant song ranking."
[3] Due to the Korean market having a more active distribution of digital music compared to physical album sales at the time of the chart's launch, initial rankings solely reflected digital sales from major music sites, as well as downloads from mobile service sites, weighted using Billboard's industry-standard formula.
[1][3] The first number-one song on the chart was "So Cool" by Sistar, on the issue dated September 3, 2011.
[8] Billboard suspended the Korean version of the chart without notice in 2022, effective the April 23 issue.
