Millions of fans around the world were asking when Game of Thrones would return. To answer them, we created a fully-interactive Facebook Live event.

To do this, we froze the Season 7 premiere date in a 4,000lb block of ice. Then invited our millions of fans to melt it with comment-powered flamethrowers.

Stars from the show encouraged fans to unlock easter eggs for more firepower. Like using the word “dracarys” to unlock two flamethrowers.

In the end, we rewarded fans with the premiere date – and a teaser for Season 7. Which quickly became the most viewed teaser in the show’s history.

We set out to up the ante for what a Facebook Live event could be. Creating an aesthetic that matched the show.

We also created interactivity in the stream, turning fan comments into fire. To do this, we tracked keywords, volume of usage and the total number of viewers. As fans commented “fire” a progress bar would charge up then trigger the flamethrower.

Stars from the show would appear with easter eggs for the viewers. Like commenting with the word “dracarys” to trigger two flamethrowers.

In under an hour, 400k+ fans on Facebook Live blasted through a block of ice to reveal the Premiere Date and a show teaser.

Then the unexpected happened: with the comments outpacing anything Facebook had ever seen (over 16,000 per minute/1.1MM in less than an hour), the world’s most powerful social network crumbled, and their live stream crashed. Twice. Yet each time it returned, even more viewers joined.
