It is interesting how the popularity of sports can be so different between Europe and North America. The most popular sports in ALL Europe is football (soccer), probably followed by tennis, cycling, and Formula 1 (as well as other motor races). In the US, soccer and F1 are far away in the popularity ranking. It is baseball, basketball, ice hockey and American football that attract the crowds and make money. And as much as European sports lack popularity in the US, the reverse is true (except for basketball).
