HBO’s “Game of Thrones” and AMC’s zombie splatterfest “The Walking Dead” were the two most-pirated TV shows worldwide in 2014 by a sizable margin, with episodes of each cable series downloaded via torrent networks about 48 million times last year.

The data comes from piracy-tracking firm Excipio, which analyzed activity for the period between Jan. 1 and Dec. 24, 2014. Excipio provided the report exclusively to Variety.

It’s no surprise “Game of Thrones” took 2014’s TV piracy crown, as the HBO epic has been a perennial favorite among digital pirates. The show’s season four premiere in April hit record levels of torrent downloads. While HBO is concerned about piracy, Time Warner CEO Jeff Bewkes has pointed to promotional upside of the phenomenon; in 2013, he quipped that piracy of “Thrones” was “better than an Emmy” as far as generating buzz.

Meanwhile, three shows from youth-skewing CW — “Arrow,” “The Vampire Diaries” and “Supernatural” — also were popular among pirates. Top-rated broadcast shows were also in the mix, led by CBS’s “The Big Bang Theory,” with 33.4 million pirated downloads for the year.

Among the top 10 pirated TV shows of the year, Brazil was home to the largest number of total downloads (28.4 million overall), followed by Russia (28.1 million), India (16 million), Australia (15.4 million), China (14.9 million) and the U.S. (14.4 million), according to Excipio. That suggests piracy in many territories is fueled by the fact that current American television shows aren’t available through legal channels.

Here are the top 10 pirated TV shows of last year, ranked by number of worldwide torrent downloads:

1. “Game of Thrones”: 48.369 million (HBO)
2. “The Walking Dead”: 47.642 million (AMC)
