I'm not sure if I saw it a in a movie but when a bunch of football or was it baseball supporters were not allowed to drink beer their conclusion was that the sport was boring without getting drunk. I think that sums up perfectly why the majority of the people outside the US don't care, don't get or just look down on typical American sports like American football. Most think calling it football is silly since you don't really go around kicking the ball that much. I believe gridiron is the correct definition but hardly anyone calls it that and that's why football as known by the rest of the world is called soccer in the US. Also American football clearly stems from the British sport known as Rugby. I see markus already explained it clearly :)


Baseball and it's variant softball also stems from a British sport (cricket). Neither of these can compete worldwide with more global sports like soccer, athletics, tennis, cycling and basketball. NBA is actually very popular outside the US too. I must say the NBA Jam videogames on snes and Sega genesis 2 vs 2 I really enjoyed.


But is your topic now about commercials or trailers? I know they are kind of similar as both promote a product so that people will buy it (or in case of a trailer people will go to theater to see it).
