Reality TV show: American Idol (2002)

American Idol's inaugural winner didn't need to keep up reality appearances in order to remind the world she existed. It's been 10 years since Kelly Clarkson was crowned and she's still churning out chart-toppers. Not only has she sold millions of albums and hit singles since releasing her first in 2003, but she's got two Grammy Awards to show for her efforts—not an accolade too many reality stars can claim.
