Super Bowl
The Super Bowl is the annual championship game of the National Football League (NFL). The game is the culmination of a regular season that begins in the late summer of the previous calendar year.
In addition, the Super Bowl has frequently been the most-watched American television broadcast of the year; the seven most-watched broadcasts in U.S. television history are Super Bowls. Normally, Roman numerals are used 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.
Early Super Bowls featured a halftime show consisting of marching bands from local colleges or high schools; but as the popularity of the game increased, a trend where popular singers and musicians performed during its pre-game ceremonies and the halftime show, or simply sang the national anthem of the United States or "America the Beautiful" emerged.
