The first series of the programme began on 12 May 2010, under the title of "Junior Apprentice", consisted of 10 candidates split evenly between gender, and ran for a total of six episodes. It also marked the debut of Karren Brady as Margaret Mountford's replacement, after she left the main show following the fifth series; Brady would later begin her first appearance on "The Apprentice" at the start of its sixth series. The spin-off later led to the BBC commissioning two more series, though with a few changes – the show was renamed as "Young Apprentice", with the number of candidates increased to twelve and the number of episodes increased to eight. The second series began airing on 24 October 2011, while the third began on 1 November 2012.
