Quoted from TheLaw:Walking Dead came out during season 4 of the show I believe, Still very much on it's way up or near the top.
Avengers came out in 2012 which I believe is the same year as the movie.
jcg9998 mentioned GOT which for sure was at it's height
Family guy was still cooking...I mean it's still on 15 years later
Avengers for sure. I wish they'd release an Infinity Saga pin. Dream theme for me. Iron Man is another that increased. Came out in 2010 with elements of the first 2 movies in it. In the summer of 2013, Iron Man 3 made more worldwide box office than both 1 and 2 combined. GOT climbed higher in ratings setting new series records in the subsequent 3 seasons post 2015 game release. I'd put Spider-Man in this category too, though this has more to do with the character in general than the original movie trilogy gaining more steam post-2007 pinball release. Either way, this is an interesting topic that I never really thought about. Wonder where Sopranos falls into this?
