Hiroshi Yamauchi
In 1992, Smulyan's ownership group sold the Mariners to the Baseball Club of Seattle, a consortium led by Hiroshi Yamauchi and later Nintendo of America. Almost immediately, the new ownership group began campaigning with local and state governments to gain public funding for a new stadium. (In 2016, Nintendo of America sold most shares of Seattle Mariners ownership held by it to a new ownership group, though Nintendo retained a 10% ownership of the team after the sale was completed.)
