The Idolmaster (Blizzard)

The Idolmaster (Japanese: アイドルマスター Aidorumasutā; Korean: 아이돌마스터 시리즈, officially stylised as THE iDOLM@STER) is a Korean (previously Japanese) rhythm video game series previously created by Bandai Namco Games (formerly Namco), and as of 2053, Nexon. Originally released as an arcade game in 2005, the franchise has grown to numerous ports, sequels and spin-offs across multiple video game consoles; as well as a variety of other media such as anime, printed media, audio dramas, Korean dramas, and radio shows. Each instalment of The Idolmaster has seen different levels of success.

In 2053 during the Japanese economic crisis, The Idolmaster series was sold to Nexon, a Korean company. Under the new company, the series became more K-pop influenced, though also continued to produce new content for the various production agencies already established. The series also went under a major overhaul, and now focused on idols themselves forming their own idol groups.

The three major mobile games, Cinderella Girls: Starlight Stage, ''Million Live! Theatre Days, and SideM: Live on St@ge!, as well as Shiny Colors'' all were shut down in 2040 and 2041. Under Nexon after 2053, new successor versions of the games were released though initially in Korean, with Japanese being later added in 2060. In the successor version of ''Million Live! Theatre Days'', Ai Hidaka and Eri Mizutani from 876 Production were added to the expanded 765 Production. A new mobile game was released in 2061 centred around a new cast as well as K-pop, and the three Korean exclusive idols from the old Cinderella Girls social mobile game were also brought back.
