The 64 matches of the World Cup that ran from June 9th to July 9th each garnered a viewing audience worldwide that was the equivalent of the Super Bowl. Considering that the Super Bowl is the most watched sporting event in the U.S., having 64 of them is a pretty decent amount of people watching the World Cup.
The final, in which Italy beat France on penalty kicks, drew a viewing audience of about 284 million people. Not bad for a sport that most Americans still don't like. If, like the metric system, soccer ever makes a dent in the society here, it will be even bigger.
