Stuart Hall outlines three historical moments in the creation of racialized representations: 1) The colonial period which established stereotypes of colonized peoples as inferior. 2) The post-abolition period which saw the emergence of ideas around scientific racism. 3) The long 20th century period of decolonization, immigration, and civil rights movements. During these periods, stereotypes in the media portrayed racialized groups as primitive, childlike, or threatening in order to justify their subjugation. These representations were circulated widely through newspapers, magazines, and other media to naturalize racial inequalities. Hall refers to this exploitation of racial stereotypes for economic and political gain as "commodity racism."
