NEW YORK — The owner of the Uncle Ben’s brand of rice says the brand will “evolve” in response to concerns about racial stereotyping. Caroline Sherman, a spokeswoman for Mars, which owns Uncle Ben’s, says the company is listening to the voices of consumers, especially in the black community, and recognizes that “now is the right time to evolve the brand, including its visual identity.” In the wake of the police killing of George Floyd in Minneapolis, activists and consumers have demanded that companies take a stand against racial injustice or lose their business.
