In professional American football, the Pro Bowl is the all-star game of the National Football League (NFL). Since the merger with the rival American Football League (AFL) in 1970, it has been officially called the AFC–NFC Pro Bowl, matching the top players in the American Football Conference (AFC) against those in the National Football Conference (NFC).
Unlike most other North American sports leagues, which hold their all-star games roughly midway through their respective regular seasons, the Pro Bowl is played around the end of the NFL season. Between the 1970 merger and 2009, it was usually held on the weekend after the Super Bowl. Since 2010, the Pro Bowl has been played on the weekend between the Conference Championship games and the Super Bowl.
The Super Bowl is the annual 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 1966 regular season, while Super Bowl XLVII was played on February 3, 2013, following the 2012 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 the 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. Currently, the National Football Conference (NFC) leads the league with 25 wins to 22 wins for the American Football Conference (AFC). The Pittsburgh Steelers hold the record for Super Bowl victories with six.
