HBO has announced that they will be developing two more seasons of Game of Thrones. That will take us through season six, I think they will renew the show all the way to the end.
The premiere of season four drew in HBO’s biggest audience numbers since The Sopranos in 2007.
HBO Programming president Michael Lombardo made the announcement, saying,
“Game of Thrones is a phenomenon like no other, [Series creators] 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.”
