You know you’ve got a hotly-anticipated show on your hands when viewers crash the system on premiere night. So many fans tried to stream “House of the Dragon” on Sunday night that HBO Max crashed, leaving thousands of users unable to watch the first episode when it was released. HBO says only a “small portion of users” were affected, and the numbers back them up; the first episode of the “Game of Thrones” prequel drew 9.986 million viewers on Sunday, making it the largest audience for any new original series in the history of the streamer.
