My guess is tennis, in terms of spectators. Table tennis, a niche sport in USA, is popular in the rest of the world in terms of participants.

NFL all the way.

Enjoyed it so much decided to join the local Highland Wildcats Gridiorn team.......Americain Football hurts like f*** though.

Quote from AlienT. :

Hey I play rounders in the garden with my daughter and she is 13 so your wrong about stopping playing at 10.

Tell her to grow up and buy her some ice hockey gear

NFL and the ALMS, the rest doesn't float my boat...

Female mud wrestling.

Mice hockey.

Basketball or Ice Hockey for me

btw, only the US make "National World Championships" in something

Basketball is pretty popular in the UK, alot of leagues and teams, especially for younger people.

Also, the same goes for Ice-hockey.
