Victorious (stylized as VICTORiOUS) is an American sitcom created by Dan Schneider that originally aired on Nickelodeon, debuting on March 27, 2010, and concluding on February 2, 2013 after four seasons. The series revolves around aspiring singer Tori Vega (portrayed by Victoria Justice), a teenager who attends a performing arts high school called Hollywood Arts High School, after taking her older sister Trina's (Daniella Monet) place in a showcase while getting into screwball situations on a daily basis. On her first day at Hollywood Arts, she meets Andre Harris (Leon Thomas III), Robbie Shapiro (Matt Bennett), Rex Powers (Robbie's puppet), Jade West (Elizabeth Gillies), Cat Valentine (Ariana Grande), and Beck Oliver (Avan Jogia). The series premiered after the 2010 Kids' Choice Awards. The series won Favorite TV Show award at the 2012 Kids' Choice Awards and 2013 Kids' Choice Awards, beating out iCarly. Victorious earned four Emmy nominations.

On August 10, 2012, Justice stated that the series would not be renewed. After the spin-off series Sam & Cat was announced, fans of Victorious expressed dismay that its spin-off series was the reason for its ending, but Schneider himself stated otherwise. Although the Victorious cast only filmed three seasons, when the decision to end the series was made, Nickelodeon split the third season in half, making a fourth season.
