Competitive Advantage
Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869, predating the formal establishment of MLB itself. MLB survived both the Great Depression and World War II without any teams folding, unlike major leagues in other sports. The Black Sox Scandal of 1919 led to the creation of a powerful commissioner position with near-unlimited authority, fundamentally transforming the sport's governance. Jackie Robinson breaking baseball's color barrier shortly after World War II was a watershed moment in both sports and civil rights history. The 2006-07 Mitchell Report found that players from every single MLB team had used steroids or performance-enhancing substances.
