Two white men, including the woman’s husband, were acquitted by an all-white jury.
Till’s body was recovered and returned to Chicago, where his mother, Mamie Till, insisted on having an open casket at his funeral. The pictures of his battered body helped push civil rights into the cultural conversation.
Music and media industry executive Paul Porter, who comments on music issues on his website, RapRehab.com, said he thought PepsiCo’s decision was an effort by the company “to do the right thing now.”
Mr. Porter, who had complained publicly and to PepsiCo about Lil Wayne and the Mountain Dew video by Tyler, the Creator, said the company is “doing a whole evaluation of the process” involving its commercials and musicians. His comments were based on his conversations with the company.
Earlier this month, Rick Ross also lost his deal with Reebok after he rapped about raping a woman who had been drugged. As for the Mountain Dew ad by Tyler, the Creator, PepsiCo said it pulled the spot immediately after learning people found it offensive.
The ad portrayed a battered white woman being urged to identify her attacker from a lineup of black men and a talking goat that has appeared in other Mountain Dew ads. Tyler, the Creator has noted that the men in the lineup were played by his friends and members of Odd Future, a Los Angeles-based rap collective.
