[|Human|] Why is football called soccer in the US?
[|AI|] It is originally a British name. âAssoccerâ (association football) was later shortened to âsoccerâ. The American football is called rugby football. Later British changes the name to football due to anti-americanism. But in America, football is named as a more popular sports like rugby football. So now it cannot change the name as the world called.
