‘Eff your sponsors’: Boycott of Megyn Kelly advertisers takes shape on Twitter after she defends blackface

NBC's host Megyn Kelly may soon be facing a boycott after she defended "blackface" Halloween costumes on Tuesday.

During her Tuesday Today Show program, Kelly asked a panel of white guests to explain why blackface is considered racist.

“What is racist?” Kelly said to her panel. “You do get in trouble if you are a white person who puts on blackface on Halloween, or a black person that puts on whiteface for Halloween. Back when I was a kid, that was okay, as long as you were dressing up as, like, a character.”

Several hours later, outrage on Twitter had turned to talk of a boycott of Kelly's advertisers.

Sponsors like Dell, Chubb North America, Crest, Ameriprise Financial, Salonpas, Allstate, Geico, Liberty Mutual and Progressive Insurance have all been mentioned as targets because they advertise on NBC.

Anticipating a financial backlash, Kelly has apologized for her remarks in an email to colleagues.
