This week, Facebook took its users to the land of Westeros, with an interactive version of Game of Thrones opening-sequence map.
The video let viewers peek in every direction at the familiar 3D mechanical map that depicts the mythical world.
Facebook CEO Mark Zuckerberg said the clip is the most-watched 360-degree video ever on Facebook, clocking up 5.3 million views in 24 hours.
At the time of writing, the video has earned 25,000 comments and 65,000 shares.
The show’s opener often holds clues about what will take place in the upcoming episode, and the interactive map on Facebook is a playground for fans hunting for hints about the series’ coming Season 6, set to premiere on April 24.
Competing directly with rival YouTube, the social network has quickly ramped up video viewing on Facebook to 100 million hours every day.
Virtual reality is one of Facebook’s key strategies in the future after buying virtual-reality headset maker Oculus $2bn in 2014.
