Game of Thrones will have two new series – Seasons 5 and 6 – producers have confirmed.
“Raise a glass of Dornish wine. Game of Thrones is renewed for seasons five and six,” the show posted on its official Facebook page.
The statement added: “Send a raven and spread the word across the realm.”
Game of Thrones Season 4 premiere gave HBO its top ratings since The Sopranos finale in 2007, it was announced earlier this week.
An average of 6.6 million watched HBO for the hit fantasy drama.
The Sopranos drew 11.9 million viewers for its final episode, according to the cable channel.
George RR Martin, the author of the A Song of Ice and Fire novels on which the program is based, is also an executive producer on the show.
He has previously hinted at the possibility of a feature film to round-off the adaptation of his book.
Game of Thrones also holds the record for the most illegally downloaded TV program.
In 2012, one episode of Game of Thrones racked up 4,280,000 illegal global downloads, according to Torrentfreak. That was slightly more than its estimated US TV audience.
Earlier this week the digital service for television channel HBO was forced to apologize to customers, after the site crashed following high demand for the series four premiere.
HBO GO asked fans to wait for a later replay of the episode on the cable channel.
Last month, the service also crashed after demand to watch the finale of True Detective.
