"Game of Thrones" is one of the most followed, if not the biggest, show there is today. Apart from being the talk of the town for killing off Jon Snow, the show's fifth season had an average of 20 million viewers tuned in, according to The Guardian.

The HBO knockout, which is based on the bestselling book series written by George RR Martin, also received insane 24 Emmy nominations. One of which might eventually hail the show as the best drama.

This is why it is isn't surprising that HBO is ready and very open to lengthen the mega successful fantasy series to eight seasons at the least. There were previous reports the show will wrap up by season 7 but Martin's stories might require more than that.

HBO programming president Michael Lombardo revealed during the Television Critics Association's press tour that the joys and tribulations in and out of Westeros might take showrunners David Benioff and Dan Weiss more than six or seven seasons to tell.

Lombardo said via Entertainment Weekly that the duo "[feels] like there's two more years after six." He, however, protested that he "would always love for them to change their minds, but that's what we're looking at right now."

"Seven-seasons-and-out has never been the [internal] conversation. The question is: How much beyond seven are we going to do? Obviously we're shooting six now, hopefully discussing seven," Lombardo further revealed.

While the HBO honcho isn't quite sure what "Game of Thrones" would be like beyond season 6, he promised, when asked of doing a prequel of the series instead, that he "would be open to anything that Dan and David wanted to do-about Game of Thrones, or any subject matter."

Lombardo said that it all depends on where the pair and Martin would want to take the series. "There's enormous storytelling to be mined in a prequel, if George and Dan and David decide they want to tackle that. For now, HBO is preparing to discuss what lies beyond 'Game of Thrones' season 7."

"Game of Thrones" received rave reviews and formed a massive following from the first season. The show is on its sixth and is still on a row with more fans going and staying in Westeros. The success of the show, however, is being challenged by the violence in it.

For Lombardo, that aspect is innate to the show and this, in part, makes it "phenomenal." He also mentioned that the show continues to "grow dramatically" and credits this to the showrunners, who were very careful in not "overstepping" the line.
