Why victorious show don't come on anymore on nickeleon?

"Victorious" ended in 2013 after its fourth season due to a combination of factors, including declining ratings and the natural progression of the show's storyline. Nickelodeon typically rotates its programming to introduce new content and keep the lineup fresh for its audience. Additionally, the cast members pursued other projects, making it less feasible to continue the series. Despite its end, "Victorious" remains popular in reruns and through its music.
