HBO also revealed that the series drew an average of 23.3 million views across all platforms this season, which include multiple telecasts and encores, VOD, its cable subscriber site HBO Go, and its standalone subscription service HBO Now. The comparable Season 4 number was 18.4 million (see "'Game of Thrones' Bigger than 'Walking Dead'?"), so the series has grown substantially in the last two years.
The show’s ratings in the 18-49 demographic were better than all other scripted shows on broadcast or cable except The Walking Dead and Empire.
Two more seasons, likely much shorter than the first six seasons, are planned (see "Final Two 'Game of Thrones' Seasons Could Be Shorter").
