Spare a moment's thought for Hiroshi Yamauchi, who passed 2 years ago. His visionary zeal and midas touch with game and console ideas took Nintendo from a backwater playing-cards company into the primary force shaping the evolution of the modern video game industry. And when his USA operating company, based in Seattle, asked him to help find a Japanese buyer for the Mariners (lest they leave the area and disappoint his many baseball-fan employees), he bought the team sight-unseen, to keep them happy. And thereby kept them in Seattle. And also enabled the flow of Japanese (and, later, other Asian) talent to come to MLB, since there was now a Japanese owner.
Criticize the managerial problems resulting from his lack of oversight if you will. He certainly was never a baseball fan, and never acted as if he were. But while TBS buying the Braves or the Tribune buying the Cubs (or Rogers Comms buying the Jays) had a profit motive attached, his purchase had, essentially, only altruistic motives. It may have motivated Henry Kaufman's entrusting the Royals to KC in perpetuity. So with today's announcement, thus ends a quite unique era in the ownership of sports, and one with many positive consequences.
