Sport Trivia
The NFL operates a developmental league, NFL Europa, with teams in five German cities and one in the Netherlands. The professional Canadian Football League plays under Canadian rules. The sport is popular as an amateur activity in Mexico and American Samoa and to a lesser extent in Japan, Europe, Korea, New Zealand and Australia.
Despite this, the game has been slow to catch on in most countries where soccer is already established as the most popular sport. Chief among criticisms of the gridiron game is the amount of time elapsing between plays and the number of interruptions in the game for time outs, penalties, out-of-bounds plays and the ease of determining how much time is left to play in the game.
