I ran into this video on youtube. It confirms what I've always thought. Batman and Spiderman are the most most popular Superheroes. Superman is third, but his popularity has waned in recent years. Iron man has had a jump in popularity in recent years but looks like he might take a dive once RDJ stops playing him. Wonder Woman is the most popular female hero her popularity seems to fluctuate between fourth and eighth. Hulk as a very similar trajectory to Wonder Woman, with sudden peaks of popularity followed by long stretches of relative obscurity. Deadpool seems to be the rising fad towards the end of the video.
