Choirock Contents Company

Choirock Contents Company is a South Korean toy and animation company founded in 2007 by Sonokong's former CEO Shin Gyu Choi. Though in its initial years from 2013 Sonokong would distribute Choirock's new toys like Hello Carbot and Turning Mecard to great success until Choirock could stand on its own, and their in-house brands are popular to this day a decade in.

(Infamously, Mecard was brought to the United States in 2018 by Mattel and sued by Spin Master falsely claiming they were infringing on Bakugan patents.)

In 2024, Choirock would acquire the rights to distribute Hasbro's Transformers and other brands in Korea, taking over from the Hasbro Korea division. Fittingly poetic.
