About the Work

As the world’s #1 language learning app, Duolingo knows entertainment content drives interest in language learning and vice versa. So when HBO Max announced a new prequel to the Game of Thrones series named House of the Dragon, Duolingo saw an opportunity to join the conversation and drive brand awareness. How? By speaking the show’s language. For the new Game of Thrones prequel House of the Dragon, Duolingo partnered with HBO Max to create High Valyrian lessons that teach fans the fictional language from the show. We developed the lessons with the inventor of the language, David Peterson, and featured real phrases from episodes. To launch the course, we bombarded Times Square and Comic-Con with cryptic billboards written all in High Valyrian, hosted a learning challenge with a life-size Valyrian Steel sword as the prize, and filmed viral content of Duo the Owl on the iron throne at HBO Max’s San Diego Comic-Con activation. “High Valyrian Lessons” became the #1 most talked about campaign for Duolingo ever and helped drive fans to HBO Max’s most watched premiere in history. The unexpected partnership generated more than 150 press mentions and 700M earned media impressions around the world with a single TikTok video from the campaign receiving 10.8M views alone. One learner even decided to hold her entire wedding in High Valyrian. So far over 300,000 fans have started learning High Valyrian, but most importantly 43% of them will go on to learn another real language like Spanish or French next.
