Last week, the sixth season of "Game of Thrones" premiered to record ratings in the United States. When factoring in all the ways people watch it — live as it airs and streamed later — the episode titled "The Red Woman" brought in 10.7 million viewers, beating the 10.3 million record set by last year's fifth season finale.

Around the world, the fifth season saw an average of 20 million viewers per episode. The show is considered a global phenomenon with sizeable fan bases in North America, Europe, Australia and South America.

The fantasy drama, adapted from the "A Song of Ice and Fire" book series by George R.R. Martin and airing on U.S. cable channel HBO, reportedly has two years left before coming to a close. But as the series starts to wind down overseas, here in Japan the push to promote it is really just getting started.
