"The company was founded on October 1, 1960 as Toshiba Musical Industries (東芝音楽工業株式会社). From 1962, it licensed Columbia (UK) titles for release in Japan. After an injection of capital by Capitol EMI, EMI divested 50% in October 1973, and the name was changed to Toshiba EMI Limited. On October 3, 1994, the equity ratio of the company was changed, in which EMI divested 55%, and Toshiba divested the remaining 45%. On June 30, 2007, Toshiba Corporation sell the remaining 45% stakes in the company to EMI, which means EMI has owned 100% of Toshiba-EMI and the Japanese branch of EMI is renamed EMI Music Japan."
