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.
