Game of Thrones is the last popular show. It is the last show that you can ask anyone about and they will know something about it. It captured a wide audience before video streaming services with their massive libraries catapulted into ubiquity and fragmented viewers that shows like Lost once united.
GoT is a complex and sprawling epic that tapered off at the end, but no one will doubt its ambition and cultural impact. Its legacy will be cemented in television history.
