So far: All of the winners (For at least some amount of time, although some have faded after their brief success.) and a few runner-ups, and a few other contestants that didn't even make it to the top 2. All of them, though, are pretty good. American Idol people are probably the most talented you'll find. I don't know all of them, but I'll list some: Carrie Underwood, Chris Daughtry, Kelly Clarkston, Jordin Sparks, Clay Aiken, David Cook, David Archuleta, and Kellie Pickler. Just note that not ALL of them are that successful CURRENTLY, but at some time they did have alot of fame. However, some others DO have that currently. Carrie Underwood, Chris Daughtry, Jordin Sparks, David Cook, David Archuleta, and Kellie Pickler just as some examples of those who are still popular NOW. It doesn't seem like any of them will go soon.
