Career

2008–09: Discovery and My World

While searching for videos of a different singer, Scooter Braun, a former marketing executive of So So Def, clicked on one of Bieber's 2007 videos by accident. Impressed, Braun tracked down the theater Bieber was performing in, located Bieber's school, and finally contacted Mallette. Mallette was reluctant because of Braun's Jewish heritage; she remembered praying, "God, I gave him to you. You could send me a Christian man, a Christian label! ... you don’t want this Jewish kid to be Justin’s man, do you?” However, after praying with her church elders and receiving their encouragement, she permitted Braun to fly Bieber, then 13, to Atlanta, Georgia, to record demo tapes. A week after arriving, Bieber sang for R&B singer/songwriter Usher. Bieber was soon signed to Raymond Braun Media Group (RBMG), a joint venture between Braun and Usher. Justin Timberlake was also reportedly in the running to sign Bieber, but lost the bidding war to Usher. Usher then arranged an audition with Antonio L.A. Reid of Island Def Jam Music Group, who signed Bieber to Island Records in October 2008 (resulting in a joint venture between RBMG and Island Records). At that point, Bieber and his mother moved to Atlanta, also the home of Usher and Braun, to base his career. Braun became Bieber's manager.
