Major League Baseball (MLB) is North America’s premier professional baseball organization, renowned for its rich history, global influence, and innovative approach to sports business and technology. Established in 1903 through the merger of the National League (founded 1876) and the American League (founded 1901), MLB is the oldest major professional sports league in the United States and Canada. Its formation marked the end of the “baseball wars” and the beginning of a unified championship, the World Series, which has become a cultural institution. MLB’s core mission is to organize, promote, and govern professional baseball, overseeing 30 teams (29 in the U.S., 1 in Canada) and a 162-game regular season culminating in the World Series. The league has pioneered numerous business and technological advancements, including early adoption of radio and television broadcasts, digital streaming, and advanced analytics in player performance and fan engagement. MLB’s embrace of data-driven decision-making and its investment in stadium technology have set benchmarks for the sports industry. Key achievements include the integration of baseball with the breaking of the color barrier by Jackie Robinson in 1947, the expansion to international markets, and the creation of the Baseball Hall of Fame. MLB’s business model, featuring lucrative media rights deals, merchandising, and global partnerships, has made it a powerhouse in the sports economy. Today, MLB continues to innovate, leveraging technology for fan experiences, player safety, and operational efficiency. Its commitment to tradition, combined with a forward-looking approach, ensures MLB remains a leader in both sports and business.
