HBO owns the rights! Come on OL. They can make 100 seasons if they want to.

HBO owns the show rights. Not GRRM. If they could continue it for as long as they wanted. They decided to end it.
Edit: GF beat me to it.
OK I did now know that. I thought it was like how JK Rowling owns the rights to Harry Potter and once the 7 books are finished, that's it, no more movies can be made.
But if you guys are right and they can make 100 more seasons, and it's still clearly commercially viable to do so, why don't they?
