There's more diversity and money now
In 1968, the St. Louis Cardinals played in Busch Stadium, which had opened two years earlier and would remain the Cardinals' home for exactly 40 seasons. The Tigers played in Tiger Stadium, which opened in 1912 -- the same day as Fenway Park -- and originally was named Navin Field (after owner Frank Navin), renamed Briggs Stadium in 1938 (after owner Spike Briggs), and finally renamed Tiger Stadium in 1961 (after owner William J. Tiger). To me it seems that the Tigers just vacated their wonderful home just a few years ago, but they actually played their last game there in 1999; this season marked their seventh in Comerica Park. And of course this season was the Cardinals' first season in their new Busch Stadium, a baseball-only venue that generates immense amounts of money with its luxury suites, specialized concessions, and commercial signage.
