Once delayed viewing is factored in, more than 10 million people will have watched the season 8 finale of 'The Walking Dead.' The show is an interesting case study in the world of Peak TV. It was a ratings juggernaut for many years, with devoted fans across the country. The numbers have slipped significantly in the past two seasons--about a third fewer people watch the show today than at its high point. But, it's still a huge, huge hit for AMC--in addition to still being the most popular show on TV for ages 18-49, it spawned the popular spin-off 'Fear the Walking Dead.' Also, a lot of fans left the show after some fan favorite characters were killed off in a particularly violent fashion, but the show aims to take a new creative, less violent direction now.
