Why is soccer not as popular in America?

Soccer is very popular in Europe, primarily England (that's where the Barclay's premier league is) and Italy. Also, in South American countries like Brazil (country with most World Cup Victories) Argentina, and Mexico. However, soccer is starting to pick up in America, the Mls league (in America) has been publicized much more on television, and on paper. The best soccer takes place in England and Italy though.
