HBO's popular show "Game of Thrones" created a buzz with its official trailer for the final season. However, it was the "Bleed for the Throne" event at SXSW music festival that truly impressed fans. Using Snapchat's AR Marker Tech Lens, HBO brought a multi-room immersive experience in collaboration with the American Red Cross. Fans had to unlock four AR experiences by scanning images scattered throughout the event. The experiences included walking through a map of Westeros and seeing a replica of the Hand of the King pin. The event aimed not only to promote the final season but also to encourage blood donation. This is not HBO's first collaboration with Snapchat, as they previously held a similar Snapchat promotion for the sci-fi series "Westworld." Apart from "Game of Thrones," other AR experiences at SXSW included Amazon's promotion of the miniseries "Good Omens" and Warner Bros.' advertising for the movie "Pokémon Detective Pikachu." Snapchat's image recognition technology has the potential to be an ideal choice for special events, outdoor advertising, and other marketing strategies. With Snapchat's AR magic, the possibilities are just beginning, even as "Game of Thrones" comes to an end.
