As far as them not having any huge stars yet I think this show is different than AI because it airs more often and we may have not given them enough time. The last show just ended in December. Just read that the 23-year-old Season 3 winner Cassadee just recently signed with Republic Nashville, joining the labelís roster of young country stars that includes Taylor Swift and The Band Perry. Don't know what will happen and we have to give her time, but I can't argue with the success of Taylor Swift or The Band Perry.
Previous winners may not have done that well, but the same could be said for X Factor and their first winner Melanie Amaro whose first single didn't go over well and her album is on hold indefinitely. I believe Jermaine Paul just released an album, but not sure how it is doing as that is not really my style of music.
Truthfully, for the most part and jmho I think country artists have an easier time to make it big sooner from these types of shows. There have been exceptions of course.
I don't know what it is, but for me I just love this show.
