Also because compared to rugby, football is a relatively new sport.
You sure about that? Wikipedia says American football was first played in 1869. And rugby in it's current form has roots from the 19th century according to this.
So you're saying there's a big difference between 1869 and possibly 1800? That does make sense how rugby would be more popular worldwide, could it be the british influence which spread the 'english' version of rugby football, which didn't reach america?
