NFL stands for National Football League, formerly known as APFA is a professional American football league founded almost a century ago on August 20, 1920. It is one of the most popular sports leagues in the United States with the highest average attendance. Today, the NFL is one of the four major professional sports leagues (MLB, NBA, NFL, and NHL) in North America.
NFL has two conferences (NFC and AFC), and 32 teams, divided equally between them. Six teams (from each conference) qualify for the playoffs. The champions of both conferences compete in the Super Bowl.
The season format consists of a preseason, a regular season, and a single-elimination playoff. The regular season begins in early September every year, in which each team plays 16 games from September to December.
The APFA arranged the first event on September 26, 1920. The 100th season of NFL will begin on September 5, 2019.
Akron Pros was the first winner of the APFA championship. AFC champion New England Patriots won the 2018 NFL championship by defeating the NFC champion Los Angeles Rams in Super Bowl LIII. With a 6-time win, the maximum championship winners are the New England Patriots and Pittsburgh Steelers.
