First four episodes of 'Game of Thrones' season 5 leaked

The first four episodes of "Game of Thrones" were leaked online Saturday as the fifth season of HBO's popular series is set to premiere Sunday night in 170 countries.

According to Tech Crunch, 50,000 people downloaded the premiere episode a few hours after it was posted on torrents. The show has long been known as being one of the most pirated shows, and often breaks torrenting records with its premiere and finale episodes.

With its newly launched HBO Now streaming service, however, the network giant hoped to lure more users to its premium direct-to-consumer streaming platform with the fifth premiere of a "Game of Thrones" season.
