Rather than an Americanization, it is argued that there is a mundialization of sports over time. Similarities in sports activities in various countries are becoming greater than the differences. Cultural diffusion is leading to a trading of sports interests in all directions, and is likely to lead to a global sports culture—modified in varying and often substantial ways by diverse colonial legacies, historical backgrounds, and value contexts. Thus the longterm trend is toward greater homogenization in world sports culture.
