What sport is often referred to as the "king of sports"?

Football, commonly known as soccer in some regions, is often referred to as the "king of sports" due to its immense popularity and widespread following across the globe. It has a rich history and is played by millions of people in nearly every country, making it the most popular sport worldwide. The FIFA World Cup, held every four years, attracts a vast audience, showcasing the sport's cultural significance and unifying ability among diverse populations.

In comparison, while basketball, rugby, and tennis have dedicated followings and their own unique fan bases, none match the global reach and influence of football. These sports certainly have their merits and appeal, but they do not command the same level of participation and enthusiasm on an international scale as football does, which establishes its title as the "king of sports."
