National Football League （NFL）

The NFL was founded in 1920 as the American Professional Football Association (APFA) before changing its name to the National Football League in 1922. It has since become the most popular and profitable professional sports league in the United States.

The league is divided into two conferences: the National Football Conference (NFC) and the American Football Conference (AFC). Each conference is further divided into four divisions, and the teams compete in a regular-season schedule of 17 games. The top teams from each division and a few wild-card teams from each conference advance to the playoffs, leading to the Super Bowl.

Throughout its history, the NFL has seen many legendary players, iconic moments, and memorable games. It continues to evolve with rule changes and advancements in player safety.

Beyond the games, the NFL has a significant impact on popular culture, with millions of fans tuning in to watch games, participating in fantasy football, and engaging in a wide range of merchandise and fan experiences.
