The league has a long history, dating back to the late 19th century, and has seen changes in rules, team expansions and player milestones over the years. It has remained a central part of professional sports, with a strong fan base and significant media coverage.
Beyond the game, MLB is involved in business partnerships, broadcasting agreements and community initiatives. It continues to be a major presence in sports, with an ongoing impact on baseball at both the professional and youth levels.
