Latest update: the respective top dancers of SNH48's 1st & 2nd teams, both being members of their elite subgroup 7SENSES, have successfully won in two talent variety shows lately &, hence, got chosen as members of two new ad hoc girl groups, respectively - a huge boost of SNH48's/SNHG's image nationwide, as well as a big push of their future careers after their graduation from SNH48 this & next year respectively (since they're 1st- & 2nd-generation members respectively).
[EDIT]
An excellent analysis & compact summary - just over 10 mins. - of SNH48's/SNHG's business model & strategies since their founding, which cover some significant milestones of their spectacular development over the years, including their "golden five years," how/why they began to go downhill last year, & their huge internal & external challenges this year, w/ the latter two forcing an important change of their operating strategy since the start of the year, i.e. sending legions of their top members to compete in three major talent variety shows (unlike numerous other idol groups, they'd never appeared on such shows before) - a must-watch if you can understand Chinese (listening Mandarin or reading Chinese subs):
^ At the ending parts of the clip, there's a comparison between the Japanese & Korean idol business models, & an explanation of why the latter prevails &, hence, SNH48's/SNHG's switching to the latter (but w/ "Chinese characteristics," which still inherit some elements of the former).
