Game of Thrones is an American medieval fantasy television series created for HBO by David Benioff and D. B. Weiss. Based on author George R. R. Martin's best-selling A Song of Ice and Fire series of fantasy novels, the first of which is called A Game of Thrones, the television series debuted in the U.S. on April 17, 2011.
Highly-anticipated since its early stages of development, Game of Thrones was well received by fans and critics. The series was picked up for a second season on April 19, 2011, two days after its premiere.
The cable television series closely follows the multiple storylines of the A Song of Ice and Fire series, and author Martin has stated that the show's pilot script was very faithful to his work. Set in the Seven Kingdoms of Westeros, where "summers span decades and winters can last a lifetime," Game of Thrones chronicles the violent dynastic struggles among the kingdom's noble families for control of the Iron Throne; as the series opens, additional threats from the snow and ice covered region north of Westeros and from the eastern continent across a narrow sea are simultaneously beginning to rise.
