A new data survey has reported that Spider-Man is no longer the favourite superhero of the US if sales are anything to go by:

Spidey's sales have begun to wane. Since 2010 comics featuring Batman in the title have sold more than those featuring Spider-man.

2012 saw 4.5m charting Batman comics being sold compared to 3.2m Spider-man comics. This represents a fall for Spidey from a height of 5.7m in 2002 - the year that the first Spider-man movie featuring Tobey Maguire was released - compared to 2.2m Batman comics.

Admittedly the correlation between comic sales and actual popularity has always been dubious, but its almost always fun to see a graph.
