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.

On June 8, 2018, HBO commissioned a pilot to a "Game of Thrones" prequel series from Goldman as showrunner and Martin as co-creator. Regarding the other four projects, HBO president of programming Casey Bloys said that some of them have been abandoned completely, while some remain as possibilities for the future. The accepted prequel will take place in the Age of Heroes, a period that begins roughly 10,000 years before the events of "Game of Thrones". Notable events of that period include the foundation of powerful Houses, the Long Night when the White Walkers first descended upon Westeros, and the Andal Invasion when the Andals invaded from Essos and conquered most of Westeros. Writing in a blog post in June 2018, Martin suggested "The Long Night" as a title for the upcoming series, and revealed that the filming location, the cast and the director for the pilot episode were yet to be determined.
