Game of Thrones (season 3)
"Game of Thrones" rapidly became a critical and commercial success after it started airing in April 2011. A few days after ratings for the second season's premiere, "The North Remembers", hit a series high of 8.3 million viewers, HBO announced the show's renewal for a third season. Prior to that announcement, there had been rumors and reports that showrunners David Benioff and D. B. Weiss planned to shoot seasons three and four simultaneously. Benioff said that this would be very efficient, but impossible to write.
Two Swords (Game of Thrones)
"Two Swords" broke the viewership record for "Game of Thrones", which was set by episode six the previous season. 6.64 million people watched the premiere airing, and when coupled with encore airings, that number rose to 8.2 million total viewers. This was at the time HBO's highest ratings for any show since the finale episode of "The Sopranos", though it was shortly exceeded. In the UK on Sky Atlantic, "Two Swords" was top in the week with a viewership of 1.21 million.
