Hello!Project

*comes up with enough courage to make this thread*

Any H!P fan can define Hello!Project in a million ways, but I'll use Wikipedia's definition because it seems to be the most straightforward:

Quote :

Hello! Project (ハロー!プロジェクト, Harō! Purojekuto) is the umbrella name for all female idol Japanese pop recording artists collective that are under contract with the Up-Front Group. The "mothership" group of Hello! Project is the super-group Morning Musume. The main producer and songwriter is Tsunku, the lead singer of Sharam Q.

And I'll quote a brief bit about their history:

Quote :

In 1997, rock group Sharam Q, fronted by Tsunku, began auditions for a female vocalist. These auditions aired via reality show Asayan, and resulted in Michiyo Heike being crowned winner. Tsunku, however, decided to give five of the runners-up, Yuko Nakazawa, Natsumi Abe, Kaori Iida, Asuka Fukuda and Aya Ishiguro, a chance to become a group in their own right. The girls were set the task of selling 50,000 copies of "Ai no Tane", their demo single, in just five days. The girls sold the required number of copies in four days, and subsequently became an official group.

(This group being called Morning Musume)

Since Morning Musume has been formed, many new members have joined, and many members have left (when a member leaves, they have a "graduation" concert). There are no more surviving original members. Throughout the years, Tsunku has also created many other groups under the same Hello!Project label.
The current lineup is as follows:
Morning Musume, Berryz Koubou, C-ute, Mano Erina, S/mileage, Hello!Project Eggs (intern members), Buono!, Shugo Chara Egg, Guardians 4, SI☆NA, Icecreamusume (Taiwan group), Frances & Aiko (Taiwan group), and Korean member Jang Da Yeon.

Members of Hello!Project have had concerts in Japan, China, South Korea, America, and France.

For the sake of this post getting too outrageous, I'll just (shamelessly) throw a few links for music videos of H!P's top selling groups.
