text: Football became popular all over the world because it started to play in England, and England had colonies all over the world and... Also some scientific researches said that football is popular because of the unpredictedness and they proved that this sport is the most unpredictable of all. And why isn't it popular in USA...I don' know. Americans are a bit odd! Just watch the Jerry Springer (it is sick) which is one of the most popular shows in the USA.
