Passage: Victorious is the fifth series created by Dan Schneider for Nickelodeon, after The Amanda Show, Drake & Josh, Zoey 101, and iCarly. Schneider first met Victoria Justice in 2005, when she was twelve and arrived to audition for the part of Lola Martinez on Zoey 101. Impressed by her energy and look, Schneider hired her and, after working with her on three episodes, called Nickelodeon to say, "I've got your next star." Justice continued her role on Zoey 101 until the series ended in 2008. In the meantime, Disney Channel, Nickelodeon's main competitor, had experienced immense success with franchises like Hannah Montana and High School Musical, which featured original songs and generated revenue through music as well as television. Seeking to "follow where the kids are", Nickelodeon executives asked Schneider to create a music-based show for the channel. Near the end of Zoey 101's run, Justice was summoned to meet with Schneider about a potential series starring her. Victorious is the first series on Nickelodeon to premiere in the decade of 2010. Big Time Rush's first episode premiered two months earlier, but its original pilot premiered in 2009.
