The sport watched the most all over the world is football (soccer). It is estimated that over 4 billion people worldwide are fans of it, so it is the most popular and most-watched sport. The FIFA World Cup and other big football events bring billions of viewers, as the final itself is viewed by enormous worldwide audiences. Some of the reasons for football continuing to dominate are its straightforward rules, the fact that very little equipment is needed, and the presence of international competitions. Other sports like cricket, basketball, and tennis have followers, but none of them are able to match football in terms of global reach and the level of viewership that is maintained over time.
