During these 100 years, the foundation for modern sports as we know them today was laid, with innovations in both the organization and commercialization of sports. Major sporting events, such as the Olympic Games and the World Cup, grew into global spectacles, uniting people from different cultures and nations in their shared love of athletic competition. The rise of professional leagues, particularly in sports like baseball, football, basketball, and hockey, not only transformed these games into national pastimes but also revolutionized the business of sports, turning athletes into iconic figures and creating a massive fan base that extended far beyond local communities.
