<< Hmm, actually "American football" is Canadian football. The CFL is the oldest professional sports league in the world!
Actually I'm not entirely sure about my first statement, anyone know the alleged beginings of football? 🙂 >>
From what I saw, American football developed out of soccer and rugby and was first played in the eastern US using some tame rules. Real professional football began in 1895. Google has a bunch of sites on Football's beginnings. I'm not that much of a football fan though, so I'm not going to read it, but it's origin's are British and American.
