#10 Whopper sacrifice Brand: Burger King / Creative Partner: Crispin Porter & Bogusky The OMFG! Factor: Sacriﬁce ten Facebook friends. Get a free Whopper. Sounds simple enough, right? But what made this campaign particularly remarkable is that it challenged the very nature of the platform on which it played out, and tapped into the essence of how social networks have changed our ideas of what “friendship” means. Whopper Sacriﬁce (a Facebook app) launched in early 2009 with little fanfare and almost no media support—and lasted only 10 days before Facebook shut it down on the basis of “user privacy violation” (the app notiﬁed friends when they were deleted). Sure, they gave away 20,000 free Whoppers. But the infamy and buzz they gained? Priceless. Steal this: • Use a really, really, really simple call-to-action. • Don’t be afraid to push the envelope.
