SUPER BOWL WINNERS DATABASE
This is a searchable database with all the super bowl winners.
The Super Bowl is the championship game of the National Football League (NFL), the highest level of professional American football in the United States, culminating a season that begins in the late summer of the previous calendar year.
The Super Bowl uses Roman numerals to identify each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15, 1967, following the regular season played in 1966, while Super Bowl XLV was played on February 6, 2011, to determine the champion of the 2010 regular season.
The game was created as part of a merger agreement between the NFL and its then-rival league, the American Football League (AFL). It was agreed that the two leagues' champion teams would play in an AFL-NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was redesignated as a "conference", and the game was then played between the conference champions (source: wikipedia.org).
