TorrentFreak reports it topped more than 8 million downloads via BitTorrent, followed by The Walking Dead (4.8m) and The Big Bang Theory (3.9m).
The season finale of Game of Thrones also set a brand new piracy record, with a quarter of a million people sharing a single file at the same time.
Online streaming and downloads for file-hosting services are not included since there are no public sources to draw data from. Total piracy numbers will therefore be significantly higher.
