The Barbie Liberation Organization, or BLO, are a group of artists and activists involved in culture jamming. Self described as "an underground network of creative activists," the group gained notoriety in 1993 after switching voice boxes in talking G.I. Joes and Barbie dolls. They resurfaced in August 2023, claiming to be the toy giant Mattel in order to announce a new collection of MyCeliaBarbie EcoWarrior Edition compostable dolls, and a corporate wide move to plastic free toy production.
