I already knew back in october, got an inside reliable source. HBO is choc full of idiot liberals but they also have a keen business sense on what works. They make money of Game of Thrones but right after, the other shows just suck ass.
believe it or not, Vikings on History beats GOT on return of investment.
True but without the popularity of GOT shows like Vikings and other clear attempts to put out something similar would likely never been made.
