While true, I find the comparison between HotD & RoP mute. At least for the current conversation. The success of one doesn't mean the other is unsuccessful. HotD having more views doesn't magically make RoP unprofitable for Amazon.

And the only measure of success Amazon & HBO really care about is the number of subscriptions each show bring. Which both claim are on the road to profitability.

Obviously, HotD won as the internets preferred show. But that doesn't inherently mean RoP is unsuccessful.
