What About the Fans?

What these numbers tell you is that baseball fans are OLD.  HALF of all fans of MLB (as of 2013, the numbers have likely only gotten worse for baseball) are over 55, compared to 37% of NFL fans and only 25% of NBA fans.  If these numbers held steady, it would indicate a looming crisis in Major League Baseball.
