PARIS (AFP) - Nearly 10 million viewers in the United States watched the eagerly awaited first episode of House Of The Dragon - the first spin-off to Game Of Thrones, making it HBO's most successful series launch, WarnerMedia said.
The original series, with its unique blend of fantasy, violence, mediaeval politics and dragons, became a global phenomenon that hooked audiences and won awards, but its 2019 finale was panned by fans and critics.
Set years earlier in the same universe of George R. R. Martin's fantasy books, House Of The Dragon depicts the glory days of the ancestors of popular Game Of Thrones characters, such as Daenerys Targaryen.
It is based on his book, Fire And Blood.
The show's premiere on Sunday evening drew 9.98 million viewers in the US across HBO's platform, making it "the largest audience for any new original series in the history of HBO", the television network's owner, WarnerMedia, said in a statement on Monday (Aug 22).
It was also the "largest series launch on HBO Max", its streaming platform, in the United States, Latin America as well as Europe, the Middle East and Africa, the US entertainment giant said.
There was "an unprecedented level" of simultaneous streams on the platform, it added.
The series has nine episodes and features Paddy Considine as the kindly King Viserys and Matt Smith as his ambitious brother Prince Daemon.
Game Of Thrones ran for eight seasons between 2011 and 2019, and other spin-offs are in the works.
The HBO show's popularity will likely be measured against The Lord Of The Rings: The Rings Of Power, adapted by Amazon Prime Video.
The Rings Of Power is set 4,000 years before the film trilogy and original books, in a fictional Second Age - a historical period sketched out in less detail by Tolkien's writings.
Amazon Prime bought the rights for US$250 million (S$348 million) almost five years ago.
It spent more than US$1 billion for five seasons of the show - each 10 hours long.
The first season will launch on Sept 2.
