"Unbowed, Unbent, Unbroken" Viewership Breakdown

The numbers are in for last Sundays episode of Game of Thrones, and once again they have fallen.  Last weeks episode "Unbowed, Unbent, Unbroken" was initially viewed by 6.24 million people during its initial airing - a slight drop from the previous week, which had 6.56 million viewers.  

It seems that this is simply becoming the trend this season, each episode suffering from a slight drop in viewership.  But even so, it still outperforms every thing else that airs on Sunday - in viewership and rating.  But next week I presume we can expect to see another drop in viewership - mainly because next weeks episode will fall on Memorial Day weekend.  

That being said, one thing that Game of Thrones is excelling in is its performance in being pirated.  Even though "Unbowed, Unbent, Unbroken" was the least watched episode of the season, it broke the record for being the most downloaded episode of all time.  Coming in with a total of 3.5 million downloads in a 24-hour period, according to Excipio.  It really seems like season 5 of Game of Thrones is becoming the season of the pirates.
