The high-budget Game of Thrones spin-off aired its second episode on HBO Max on Sunday 28 August in the US.
House of the Dragon’s second episode surpassed the record-breaking viewership figures of its premiere.
House of the Dragon’s second episode did provoke some degree of controversy among fans, however, with some viewers taking issue with the re-use of a key Game of Thrones feature.
Game of Thrones was also the second most watched programme on HBO last week.
