The day on which the Super Bowl is played is now considered to be a de facto American national holiday, called Super Bowl Sunday. Super Bowl Sunday is the second-largest U.S. food consumption day, after Thanksgiving Day. It always takes place on the first Sunday in February. The Super Bowl is the championship game of the National Football League (since 1967), the premier association of professional American football. In most years, the Super Bowl is the most-watched American television broadcast. Many popular singers and musicians have performed during the event’s pre-game and halftime ceremonies.
Exclusive television broadcast rights for the Super Bowl rotate each year among 3 of the 4 major American television networks: CBS, NBC and Fox. Because of its high viewership, commercial airtime for the Super Bowl broadcast is the most expensive of the year. Due to the high cost of investing in advertising on the Super Bowl, companies regularly develop their most expensive (and ostensibly, best) advertisements for this broadcast. As a result, watching and discussing the broadcast’s commercials has become a significant aspect of the event as well.
The Super Bowl was first played on January 15, 1967, as part of a merger agreement between the NFL and a 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 consummated. After the merger of the two leagues in the 1970s, each league became a "conference", and the game was played between conference champions. Lamar Hunt, former owner of the Kansas City Chiefs and founding member of the American Football League, coined the name Super Bowl after watching his children playing with a Super Ball. The Super Bowl uses Roman numerals to identify each game, rather than the year in which it is held. (From: Wikipedia, license: CCA-SA)
