On September 17, 2002, Kelly Clarkson released "A Moment Like This," the coronation single that quickly became a number one hit in the U.S. shortly after she won the inaugural season of American Idol on September 4, 2002. This song was pivotal not only in launching Clarkson’s career as a major pop star but also in proving the viability and popularity of the reality TV music competition format in the United States. Its rapid climb on the Billboard Hot 100, leaping from No. 52 to No. 1, broke a chart record previously held by The Beatles since 1964, cementing the show’s impact on music and television industries.

Beyond "A Moment Like This," Clarkson avoided the one-hit-wonder trap often faced by reality show winners. Her debut album Thankful, which dropped in April 2003, debuted at No. 1 on the Billboard 200 and featured singles like "Miss Independent" that achieved Top 10 status. Her 2004 album Breakaway further established her as a pop powerhouse with hits such as "Since U Been Gone," "Behind These Hazel Eyes," and "Because of You" removing any lingering doubts about her staying power and longevity in the music business beyond her reality TV origins.

Clarkson’s career evolved significantly as she transitioned from music to television. Her daytime talk show, The Kelly Clarkson Show, launched in 2019 and quickly became a critical success, earning eight Daytime Emmy wins and four consecutive hosting Emmys from 2020 to 2023. The series blended music and talk, notably featuring Clarkson’s popular "Kellyoke" covers, highlighting how television became a main platform for her talents after years of establishing herself as a recording artist. The show concluded its run after seven seasons in 2024, marking the end of this notable chapter in her career.

Continuing her television presence, Clarkson will return as a coach on the 30th season of The Voice beginning September 21, 2026. Having already coached multiple winners, she now mentors new contestants hoping to achieve the same breakthrough she did 24 years ago. This return to reality TV coaching underscores how deeply intertwined television has been with both launching and sustaining Kelly Clarkson’s multi-faceted career over more than two decades.
