Whats the Most popular Sport in America?

Whats the Most popular Sport in America? Is it the NFL?  Or how about the NBA?  I will say the Major League Baseball is the least most popular sport in America because its not as excited as the other sports.  The most popular sport in the USA is football and because of this popularity the NFL merchanise is the most popular too.

There is a ton of different types of sports stuff that fans can buy including Bobblehead dolls of their favorite sports players.  Since the NFL is the most popular sport in America you would think football bobbleheads would be the most popular type of bobblehead.   They have lots of different types of sports bobbleheads on the market.
