HBO's executives want Game of Thrones author George R. R. Martin to keep working on finishing his series just as much as you do, which should probably make you a little antsy for the future of the show. The problem has always been that Martin hasn't yet written the final two books in the seven-book series the show is based on. And he's not terribly fast at writing them: the five books so far in the series have been published over 15 years; the television show has covered almost three of those books in three years. So when asked at the Television Critics Association Press Tour yesterday about how long the show will go, the network had a clear message for Martin: "Get busy writing," said HBO programming president Michael Lombardo according to Entertainment Weekly.
HBO likely wants to hold onto their ratings bonanza and Emmys success for as long as possible. Though it's been reported that the show will last seven seasons, Lombardo said: "As far as I’m concerned, they can go on as long as there are stories to tell." The fact that there isn't a concrete plan can be worrisome for fans. Time's James Poniewozik tweeted news of the statements saying: "Is it just me, or is HBO's reassurance about Game of Thrones not running out of story less than reassuring?"
