There is definitely success beyond American Idol.
Alumni of the reality television singing competition series, which ran on FOX for 15 seasons from 2002 to 2016 before moving to ABC in 2018, have gone on to great career heights since being introduced to the American public through the hit show.
Among the winners and former contestants are Academy Award winners, Grammy Award winners, Broadway stars, Las Vegas residency performers, TV hosts, Dancing With the Stars winners and former political candidates.
Since her Season 1 win in 2002, Kelly Clarkson has reached No. 1 on the charts multiple times. She's a judge on NBC's singing competition, The Voice, and, as of September 2019, the host of her own daytime talk show.
But what about some of the singers who did not win the popular competition series?
Chris Daughtry placed fourth on Season 5 of American Idol and is a successful rock musician as the frontman of his band, Daughtry. He has even dabbled in acting, starring as Judas in FOX's live broadcast of The Passion, and he voiced Counselor Olaf in the animated film Trollz.
