An industry or a sport? The "baseball industry" refers to the balance sheets of the teams. Sponsors get revenues from sales of tickets and memorabilia (like players 'cards or autographed baseballs), advertising on uniforms and billboards at games, and television royalties. With these revenues they must cover team costs, including the field and facilities, players' salaries, equipment, and training.
所謂的「職棒產業」，指的是企業球團以「經營」球隊比賽所得到的票房，以及因為比賽而帶來的球衣、看板廣告、電視轉播權利金，或是如棒球卡、簽名球等棒球紀念品所帶來的盈收，來支付企業培養一隻球隊包括場地設備、球員薪水、裝備，以及培訓等的支出。
