It opened in 1966 and is the only remaining stadium in the United States that is shared by professional football and baseball teams. The Coliseum was also home to some games of the San Jose Earthquakes of Major League Soccer in 2008–2009 and hosted games at the 2009 CONCACAF Gold Cup. The Oakland–Alameda County Coliseum complex consists of the stadium and the neighboring Oracle Arena.
