Soccer (football) wasn’t at the very first Olympics in 1896. But it was in 1900 and every year since then. At that first event, only 3 teams competed: Great Britain, France, and Belgium. Great Britain won the gold. It’s gotten ever more popular since with women’s soccer added in 1996. At the 2016 Games, 16 men’s teams and 12 women’s teams competed with Brazil and Germany (respectively) getting gold.
