HBO on Monday promoted the Blu-ray and DVD release of Game of Thrones season four in London with a life-size ice sculpture of the Iron Throne from the hit drama. Time Warner’s HBO said it collaborated with the Glacial Art Ice Sculptors to create the throne in Covent Garden in the British capital to draw fans and raise awareness of the home video release. The company announced “fans of the show were encouraged to hashtag TakeTheThrone for one day only to mark the season-four Blu-ray and DVD release” on Monday.
