FIFA World Cup takes its roots back in 1930 and already then lots of discussions around the subject were created. The main issue was the ball choice as there was no universal shape accepted. For the final match between Argentina and Uruguay it was decided that one team chooses a ball for the first half and Argentina for the second half of the match.
The soccer ball has gone through significant changes, which are reflected below.
1994, United States
2002, South Korea and Japan
