The series aired for five seasons and 100 episodes from May 29, 2006, to November 4, 2010 on PBS, with over 30 contestants by that time. Although a sixth season was planned for early 2011, with auditions taking place in January 2010, WGBH announced on June 14, 2010, that due to a lack of funding, the series would end. It previously aired reruns on the 24 hour PBS Kids Channel from January 16, 2017 until November 20, 2018.
