Following the recent controversy over the provocative 'spread leg' choreographies by 4minute and Rania, KBS has become the first public broadcast company to ban such dance moves from their show. On April 11th, "Music Bank" PD Kwon Jae Young announced that he plans to impose restrictions on their choreography. As of April 15th, groups who do not modify their dance moves will not be able to perform on "Music Bank" next week. Kwon PD stated, "We can no longer tolerate the provocative choreography of the "spread leg" dance." He believed that he could no longer stand indifferent towards the fact that the content of "Music Bank" could have an adverse influence on the young viewers of the show. "Music Bank" currently has a age rating of 15 and over. 4minute recently came forth with an announcement that they will put in serious consideration over the modification of their 'spread leg' dance due to the controversial opinions of netizens and viewers.
