oh! another hard question to answer. many companies try to debut groups they can not fund properly sadly and yet they keep trying to make more groups if the last didn't meet their expectations in hopes the next will make them $$$. my pure assumptions, but many such cases in 2012-2013,
so many groups debuted during this era just to fade off quickly after.

groups with wonderful talent might i add, but the time, budget, era, was just not the right time for them sadly. idol life is hard to break through.
