The hit show, which airs on HBO, is an adaptation of George RR Martin's series of fantasy novels, 'A Song of Ice and Fire'. It is currently in its fourth season, said The Hollywood Reporter.
HBO programming president Michael Lombardo said that the show has become a phenomenon among the viewers.
"Game of Thrones is a phenomenon like no other. David Benioff and D B Weiss, along with their talented collaborators, continue to surpass themselves, and we look forward to more of their dazzling storytelling," Lombardo said.
