For Christmas, we decided to search for our biggest Facebook fan.

Thanks to the tool Sociograph.io, we tracked all the comments that have been posted on our page since we created it in 2013.

And we found him. Sullyvan, a French fan from Bordeaux. No one has commented our Facebook page as much as he did in 4 years.

And to thank his (extreme) love, we decided to offer him the biggest present he could ever dream of: his own Burger King. We wrapped his restaurant and changed everything inside the restaurant with his name everywhere.

Everything happened because of a single fan and a single facebook post.

On this facebook post, we broadcast a video presenting everyone our biggest fan, Sullyvan, and the incredible gift we offered him.

While all our fans were envying Sullyvan, we offer them a chance to win the same gift.

All they had to do was being the one who commented the most Sullyvan’s video.

And the least we can say is they played a lot…

In only one week, we had 366 240 comments on Sulluvan’s video making our campaign the most commented one in France in 2017.

The winner of our "engagement contest“ wrote 9 115 comments by his own.

By targeting only one special fan, we succeed to engage 4 million people.

45 million people have been reached in the end, with only one fan and only one Facebook post.
