Super Bowl XXIV was an American football game between the National Football Conference (NFC) champion San Francisco 49ers and the American Football Conference (AFC) champion Denver Broncos to decide the National Football League (NFL) champion for the 1989 season. Played on January 28, 1990 at the Louisiana Superdome in New Orleans, Louisiana, the 49ers defeated the Broncos by the score of 55–10, winning their second consecutive Super Bowl, and tying the Pittsburgh Steelers with four Super Bowl victories. San Francisco also became the first team to win back-to-back Super Bowls with two different head coaches; rookie head coach George Seifert took over after Bill Walsh retired after the previous season's Super Bowl.
