The influence of British sports and their codified rules began to spread across the world in the late 19th and early 20th centuries, particularly association football. A number of major teams elsewhere in the world still show these British origins in their names, such as AC [Athletic Club] Milan in Italy, Grêmio Foot-Ball Porto Alegrense in Brazil, and Athletic Bilbao in Spain. Cricket became popular in several of the nations of the then British Empire, such as Australia, South Africa, India and Pakistan, and remain popular in and beyond today's Commonwealth of Nations. The revival of the Olympic Games by Baron Pierre de Coubertin was also heavily influenced by the amateur ethos of the English public schools.
Baseball (closely related to English rounders and French la soule, and less clearly connected to cricket) became established in the urban Northeastern United States, with the first rules being codified in the 1840s, while American football was very popular in the south-east, with baseball spreading to the south, and American football spreading to the north after the Civil War. In the 1870s the game split between the professionals and amateurs; the professional game rapidly gained dominance, and marked a shift in the focus from the player to the club. The rise of baseball also helped squeeze out other sports such as cricket, which had been popular in Philadelphia prior to the rise of baseball.
American football (and gridiron football more generally) also has its origins in the English variants of the game, with the first set of intercollegiate football rules based directly on the rules of the Football Association in London. However, Harvard chose to play a game based on the rules of Rugby football. Walter Camp would then heavily modify this variant in the 1880s, with the modifications also heavily influencing the rules of Canadian football.
World-wide, the British influence certainly includes many different football codes, lawn bowls, lawn tennis and other sports. The major impetus for this was the patenting of the world's first lawnmower in 1830. This allowed for the preparation of modern ovals, playing fields, pitches, grass courts, etc.
Perhaps in a reaction to the demands of contemporary life, there have been developments in sport that are best described as post-modern,[citation needed] extreme ironing being a notable example. There is also a move towards adventure sports as a form of escapism, transcending the routines of life,[citation needed] examples being white water rafting, paragliding, canyoning, base jumping and more genteelly, orienteering.
