In a sense, BuzzFeed was born as a prank. For an online promotion, Nike launched a website where shoppers could personalize their shoes by selecting the color patterns and appending a nickname or chosen phrase. The 27-year-old Peretti submitted his design for a pair of shoes emblazoned with the word “sweatshop,” an obvious reference to Nike’s reputation for manufacturing its products overseas with cheap labor. An email came from Nike informing him this constituted “inappropriate slang.” The real reason for the rejection, Peretti knew, was that Nike was defensive about its sweatshops.
