It is pretty much a guarantee when I listen to a 99% Invisible episode that I'll have no prior knowledge of the topic and by the end I'll be intrigued by it and even feel like I somehow now have the authority to speak to the topic.
Personally, 99% Invisible episodes are the perfect length. Majority of the podcasts out there are an hour or longer. I usually have to break each of those up into two or three listening sessions due to my commute and schedule. Most of 99% Invisible episodes are around 20 to 30 minutes. Usually I can finish them in one setting and it's just a much more gratifying experience.
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.
