Promotions for the album started March 13 with the performance of "Sorry, Sorry" and "Why I Like You" on Music Bank. Two weeks later, "Sorry, Sorry" became the number one song of the week on the same program. During the group's performance on music program Popular Songs on March 15, ratings went up to as high as 14%, the highest in recent years. From March to May, "Sorry, Sorry" collected a total of ten #1 awards with consecutive wins. On May 12, Super Junior released their new album "It's You". The music video for the song "It's You" was released two days before schedule because it was leaked onto the internet with only 3 seconds missing so without any editing they released it. Three days later they released what they called "It's You (Drama Version)". A month later, on June 15, they released "It's You (Dance Version)". In the unedited and edited version Kibum only showed up in the beginning and a minute part in the middle of the videos. In the dance version Kibum again did not appear. Promotions for "It's You" ended in early June so SM could promote SNSD's new song. Super Junior is currently preparing for their Super Show tour. They will hold two concerts in Japan in August 2009.
Super Junior was also featured as one of the dance contestant groups on Randy Jackson's ABDC(America's Best Dance Crew)
From Wikipedia:Super Junior (Korean: ?????), often referred to as SJ or SuJu (??), is a popular boy group from South Korea formed by SM Entertainment in 2005. With a total of 13 members, they are one of the largest boy bands in the world. The group consists of Leeteuk (leader), Heechul, Hankyung, Yesung, Kangin, Shindong, Sungmin, Eunhyuk, Donghae, Siwon, Ryeowook, Kibum and Kyuhyun. The only Chinese member, Hankyung, was chosen from three thousand applicants via auditions held in China by SM Entertainment in 2001. As of 2010, only 10 members are active, due to Hankyung's ongoing lawsuit against SM Entertainment, the personal activities of Kibum in acting, and Kang-in's leave of absence for mandatory military service. However, the remaining members have insisted that they are still part of the group.
Super Junior has released and contributed in 20 different kinds of records with varying degrees of success. Over the years, they have been divided into smaller sub groups, simultaneously targeting different music industries and audiences. Largely due to Super Junior's success as entertainers, other Korean entertainment managements began to train their music groups in other areas of entertainment, such as acting and hosting. In addition to their commercial success, Super Junior has earned seven music awards from the M.net Asian Music Awards, eleven from the Golden Disk Awards, and is the second singing group to win Favorite Artist Korea at the 2008 MTV Asia Awards after JTL (consisting of Jang Woo Hyuk, Tony An and Lee Jae Won of H.O.T) in 2003.
