This can be seen as either discounting some of the ancient games of cooperation from Asia (e.g. polo, numerous martial arts forms, and various, now assimilated football varieties) and even from the Americas (e.g. lacrosse), or as the suggestion that while these sports did exist modern team sports did not directly derive from them. European colonialism certainly helped spread particular games around the world, especially cricket (not related to baseball), football of various sorts, bowling in a number of forms, cue sports (like snooker, carom billiards and pool), hockey and its derivatives, equestrian (originally of Middle Eastern origin), and tennis (and related games deriving from jeu de paume), and many winter sports. The originally Europe-dominated modern Olympic Games generally also ensured standardization in particularly European, especially British, directions when rules for similar games around the world were merged.[20] Regardless of game origins, the Industrial Revolution and mass production brought increased leisure which allowed more time to engage in playing or observing (and gambling upon) spectator sports, as well as less elitism in and greater accessibility of sports of many kinds.
