The National Football League (NFL) is a professional sports league that plays American football. All 32 teams are based in the United States. The offices of the NFL are in New York City.
The league has two conferences: the National Football Conference (NFC) and the American Football Conference (AFC). The season starts on the weekend after the first Monday in September. The playoffs start in January. The winners of the AFC and NFC championship games compete in the Super Bowl in February.
It is one of the Big Four sports leagues in the U.S. The others are Major League Baseball, the National Basketball Association, the National Hockey League. Some might say Major League Soccer might be up there, but most consider those main 4 the Big Four sports leagues. It is the sports league with the highest number of people in the U.S. watching on television. It also has the highest average number of people attending each game. Super Bowl Sunday is an unofficial national holiday in the U.S. It is watched by more people than any other American television program.
In terms of number of players and people involved, the NFL is the largest professional sports league in the world. It is widely considered the top level of competition in the world for American football.
In 1920, an American football league was formed. It was called the American Professional Football Association. In 1921 it changed its name to the National Football League. In 1960 another league was formed, called the American Football League. In 1970 the National Football League and the American Football League merged so that the teams from each league could play each other. The league called the National Football League changed its name to the National Football Conference (usually called the NFC) and the league called the American Football League changed its name to the American Football Conference (usually called the AFC). The two conferences together are now called the National Football League. People can also call it by the acronym NFL for short.
Due to the U.S. being a large country, it would be hard for teams to travel a long way to play other teams, therefore, the teams are separated into smaller regional divisions based on where they are in the country. The teams are separated like this:
Teams in the AFC
AFC East
AFC North
AFC South
AFC West
Teams in the NFC
NFC East
NFC North
NFC South
NFC West
The teams in the NFL play games against each other from September to January. This time is called a season. Each team plays 17 games, most recently increased from 16 starting with the 2021 season. This is how which games a team will play are chosen:
Since the 2006 season, the NFL has used a "flexible scheduling" system for the last seven weeks of the regular season where there is a Sunday night game. The system is designed so that the league has the flexibility in selecting games to air on Sunday night that will feature the current hottest, streaking teams.
Under the system, all Sunday games in the affected weeks will tentatively have the "early" start time of 1 p.m. ET/10 a.m. PT, except those played in the Pacific or Mountain time zones, which will have the tentative start time of 4 p.m. ET/1 p.m. PT. On the Tuesday 12 days before the games, the league will move one game to the prime-time slot, and possibly move one or more 1 p.m. slotted games to the 4 p.m. slot. During the last week of the season, the league could reschedule games as late as six days before the contests so that as many of the television networks as possible will be able to broadcast a game that has playoff implications.
At the end of every NFL season, the eight teams that finish the season at the top of their divisions and three teams from each conference that were the best teams apart from the eight division winners (these six teams are called Wild Cards) enter a competition to see who is the best team in the whole league. This is called the Playoffs. There are a total of 14 teams in the Playoffs, seven from both the AFC and NFC. The seven teams in each conference are listed in order of how well they played in the season. This is called seeding and it is done to make it easier for the better teams to win. The teams that did not win their leagues (the Wild Cards) are always the bottom three seeds in the list, even if one or more had a better record than a team that won its division.
The first round of the playoffs, known as Wild Card Weekend, features six games. The matchups by seed are the same in both conferences.
The winners of each game advance to the next round; the losers' seasons end. This leaves 8 teams.
The second round, called the Divisional Playoffs, has four games. Again, the matchups by seed are the same in both conferences.
As in the previous round, only the winners advance to the next round.
The third round, the Conference Championship Games, involves two games.
The last part of the playoffs is called the Super Bowl. The AFC Champion and the NFC Champion teams play each other to decide who is the best team in the NFL. The team that win the Super Bowl claims the Lombardi trophy.
