Music Bank( Korean : 뮤직뱅크) is a South Korean music television program broadcast by Korean Broadcasting System, KBS . It airs live every Friday at 6:10 PM KST. It is currently hosted by Lee Jang-woo and UEE . As of 2011, it is broadcast in 72 different countries through KBS World , owing to its popularity of K-pop in foreign countries.
Prior to Music Bank, Top 10 Songs (가요톱10) debuted in 1981 airing live at 6:30PM on Fridays and aired until 1998. For the first few months of 1998, Bravo New Generation took its place, but due to low ratings, it was quickly replaced by Music Bank on June 18, 1998. The chart format that was used since Top 10 Songs was abandoned in late 2001 due to controversy and was changed into a request format.
In 2005, the show was moved to Sunday afternoons at 12:45PM and became a recorded broadcast. Due to sinking ratings, in September 2007, the show returned to its original timeslot of Fridays evenings at 6:30 PM and returned to a live format. The charts were revived as category-based charts.
In January 2008, the category-based charts were combined into the K-Chart which is the familiar countdown chart and the only program to do so. In June 2008, the show extended to 70 mins, airing from 6:30 PM to 7:40 PM making it the longest music program on air. In November 2008, as part of the Autumn format changes, the show began airing from 6:40 PM to 8:00 PM for 80 mins. In May 2010, as part of the Spring format changes, the show began airing from 5:50 PM to 7:10 PM for 80 mins.
On August 27, 2010, Music Bank began airing live to 54 different countries around the world through KBS World, and included new interactive features for international viewers through Twitter.
On November 11, 2011, as part of the Autumn format changes, the show began airing for 105 mins from 6:10 PM to 7:55 PM.
K-Chart is the countdown charts of Music Bank. The charts are calculated by combining the Digital Music Charts (65%), Album Sales (5%), Number of times broadcast on TV/Radio (20%), and Viewers Choice Charts (10%). The Top 50 songs of the week are featured on the show, where the Top 21-50 songs are shown via marquee and the Top 20-3 songs are featured by the hosts. The hosts then showcase the Top Two songs and announce who will be the winner of the week. The Number 1 song on the chart is the winner of that week's chart and receives an award.
During the last week of June, the Music Bank First Half 1st Place award is awarded to the most popular song of the first half of the year. During the last week of December, theMusic Bank 1st Place award (or Music Bank MVP in 2008) is awarded to the most popular song of the entire year.
Prior to the combined K-Charts, category-based charts were used. From September to December 2007, every week a different category (Digital Music Charts, Karaoke Charts,Viewers Choice Charts, Album Sales Charts) was featured. Technically, each category would only be featured once a month. It was similar to K-Chart except the results each week could only be based on a specific chart, and not all the charts combined. From January 2008 to April 2009, two charts were used. Every week, the Digital Music Charts and Album Sales Charts were used, and at the end of the month were the combined charts (Album Sales Charts (20%) + Digital Music Charts (50%) + Viewers Choice Charts (30%)). In May 2009, this was abandoned for the combined charts featured every week.
