 Later venues such as Cleveland Stadium, Milwaukee County Stadium and Baltimore Memorial Stadium were built to accommodate both baseball and football.In the 1960s, multipurpose stadiums began replacing their baseball-only and football-only predecessors, now known as "classics" or "jewel box" parks.The advantage to a multipurpose stadium is that a singular infrastructure and piece of real estate can support both teams in terms of transportation and playing area, and money (often public money) that would have been spent to support infrastructure for two stadiums could be spent elsewhere.
