High Quality Content by WIKIPEDIA articles! Multi-purpose stadiums are a type of stadium designed for use by multiple sports. In North America, multi-purpose stadiums were built primarily during the 1960s and 1970s as shared home stadiums for Major League Baseball and National Football League or Canadian Football League teams. Some stadiums were renovated to allow multi-purpose configurations during the 1980s. As multi-purpose stadiums were rarely ideal for both sports usually housed in them, they fell out of favor by the 1990s. With the opening of the Truman Sports Complex in Kansas City, a model for purpose-built stadiums was laid down. Since Oriole Park at Camden Yards opened in 1992, most major league sports stadiums have been built specifically for one sport.
