In Japan and Korea, idols are a huge deal.
The fandoms surrounding idols and idol groups are massive, with a ton of merch, lingo, events, etc surrounding the entertainers.
So why isn't that happening in America?
The UK tried it out with One Direction and we have a few girl groups like Fifth Harmony and Little Mix, but for the most part the classic pop group ensemble faded away in the early 2000s.
Here are a few reasons why it might not work:
I'm not saying either opinion is correct
1. The Concept of Being An Idol
public humiliationpersonal rights
a lot of personal life that shouldn't be judged by the public,
You must be a model citizen at all times
2. Company Loyalty
In America, we know the big companies like Warner, Sony, etc, but we rarely pay attention to what label each artist is on. And even if they're on the same label they don't really work together so its hard for fans to be loyal to one company.
The closest I think we can get to that is waaay back with Motown Records or more recently the bands that came out on Fueled By Ramen. Smaller hip hop labels still keep this group style too! We could actually see the connection the artists had on those labels and could support the label as well as the artists.
Now in Korea, we all know that companies are a big deal. YG Family, JYP, Cube, SM, etc. They do things together like concerts, Christmas songs, etc. We are able to anticipate the company's new project or collaboration. It's easier for the fans to get hyped over multiple groups at once.
In America, bands are usually put together by the band members. Whether they start in a garage or they put up flyers to find members, it is the band that forms first, then the label that signs them.
Idols train a LOT. Sure, in America entertainers practice, train, get vocal lessons, learn new instruments, get prepped for interviews etc but they are not forced to practice for 12 hours a day.
Living in dorms without cell phones or internet, being forced to learn languages, dances, public speaking, etc - its totally normal in the idol world. Because of this, idols should be pretty prepared for anything. I'm not so sure American entertainers would be up for this style of training.
