HBO - Fire and Ice
We love this PR / Facebook live video stunt that Unit9 created to reveal the release date for the new season of Game of Thrones. The concept was really simple, but so much fun - using Facebook's live video feature, users could activate flamethrowers that would melt the original block of ice, resulting in the date of the new season being revealed. To date, this has been the biggest Facebook live event recorded, with over 600 000 votes, 3.5 million views and 19 000 shares. That's the power of a good idea!
