HBO's Game of Thrones conducted their first major live stream marketing campaign by using Facebook Live to announce their Season 7 premiere. During the event, viewers were encouraged to comment with "FIRE" or "DRACARYS" to help burn a block of ice to reveal the premiere date. Cast members, including Lena Headey (Cersei Lannister), Nikolaj-Coster Waldau (Jaime Lannister) and Gwendoline Christie (Brienne of Tarth) showed up on the live stream to encourage comments and increase excitement. The live stream did not go as smoothly as planned, but had a certain amount of key takeaways for marketers.
