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.
George R. R. Martin
HBO Productions purchased the television rights for the "A Song of Ice and Fire" series in 2007 and began airing the fantasy series on their US premium cable channel on April 17, 2011. Titled "Game of Thrones", it ran weekly for ten episodes, each approximately an hour long. Although busy completing "A Dance With Dragons" and other projects, George R. R. Martin was heavily involved in the production of the television series adaptation of his books. Martin's involvement included the selection of a production team and participation in scriptwriting; the opening credits list him as a co-executive producer of the series. The series was renewed shortly after the first episode aired.
