Most successful 'American Idol' of all time

Kelly Clarkson held the distinction
of having the highest-selling American Idol album in the United States until November 2009, when Carrie Underwood claimed that title by a narrow margin of 100,000 albums. Clarkson, however, remains the highest-selling American Idol alum overall, with around 23 million albums sold worldwide.

In May 2010, Billboard named Clarkson the "most successful 'American Idol' of all time", factoring in album sales, singles sales, and radio plays.
