So many American artists started out on YouTube, but did you know quite a few Korean idols did the same?
Here is a list of the known YouTube channels :)
Jae from Day6
Jae from Day6 had a ton of fans pre debut thanks to his awesome acoustic covers he would put up on YouTube starting in 2010!
Vernon from Seventeen
He actually started out super young (which makes sense, cause he's STILL super young lol) and made videos as a kid with the help of his parents. The original channel is gone, but here's one video that survives!
Ailee also got discovered over Youtube where she was picked up by US talk shows like Maury. After that she headed to Korea to pursue a full-time entertainer career!
Young K from Day6
Going as Serine originally, she vlogged through her trainee days and was super open about the whole process! She vlogs less now but still has really cool videos talking about everything from a day in the life of an idol, to going through the audition process.
