The FIFA World Cup is a competition held once every four years between the best football players in the world. There have been 18 tournaments held since the first one in 1930. The World Cup has been played every four years since that date. The tournament was not played in 1942 and 1946 because of World War II. The actual tournament itself goes on for almost the entirety of the 4 years in between the finals. This time period is broken into two parts, the qualifications and the finals. The World Cup could be the most popular event in the world, with estimates of over 700 million people watching the 2006 final. Each tournament has a different location for the finals with 2006 taking place in Germany and the 2010 finals set to take place in South Africa. In order to understand just how big the tournament is one needs to look at how the teams are selected, how the players are chosen for those teams, and how the finals are played out.
