New Kids on the Block Live was the fifth concert tour by American band New Kids on the Block and the first in 14 years since the group broke up after their last tour in 1994. In April 2008, the group reunited on the Today Show, announcing a new album and tour. The tour visited North America and Europe. The tour took place from the fall of 2008 through the summer of 2010. Each year, the tour was revamped with new staging, setlist and tour name. In 2009, the tour was acknowledged as The "Full Service Tour" and in 2010, the tour was known as the "Casi-NO Tour".
