Is Piracy Helping Game of Thrones?

Here's an idea: Game Of Thrones owes its success to piracy. If you're like us, you LOVE Game of Thrones. But if you're also like us, you may not, technically, have... cable. So how are we seeing this amazing show on HBO, which is stuck behind a pay wall? A huge amount of viewers (not us of course, no no no) are downloading the show illegally.
