The Changing Cast of American Idol With 30 Judges and Their Farewells

Since its debut in 2002, American Idol has featured a diverse panel of judges, each making their mark. Simon Cowell’s direct critiques and Jennifer Lopez’s encouragement showcase their influence. Here, we explore the reasons behind the departures of 30 judges and gain insight into their contributions and exits.

Simon Cowell 

Known for his blunt and often scathing critiques, Cowell brought a unique edge to the show. His straightforward feedback stung, but it was delivered with a sense of humor that influenced audiences. Cowell left in 2010 to focus on launching his other talent shows, including “The X Factor.”

Known for his practical advice and signature phrases, he became a beloved figure on the show, remaining with the panel longer than any other original judge before leaving after Season 12.

Kara DioGuardi
