National Football League (NFL)

Major professional football organization in the U.S. It was founded in 1920 at Canton, Ohio; its first president was Jim Thorpe. In 1970 it merged with the rival American Football League (founded 1959). Beginning with the 2002 season, it was divided into two conferences, each with four divisions. The National Conference consists of the East Division (Dallas Cowboys, New York Giants, Philadelphia Eagles, and Washington Redskins), the South Division (Atlanta Falcons, Carolina Panthers, New Orleans Saints, and Tampa Bay Buccaneers), the North Division (Chicago Bears, Detroit Lions, Green Bay Packers, and Minnesota Vikings), and the West Division (Arizona Cardinals, St. Louis Rams, San Francisco Forty-Niners, and Seattle Seahawks). The American Conference consists of the East Division (Buffalo Bills, Miami Dolphins, New England Patriots, and New York Jets), the South Division (Houston Texans, Indianapolis Colts, Jacksonville Jaguars, and Tennessee Titans), the North Division (Baltimore Ravens, Cincinnati Bengals, Cleveland Browns, and Pittsburgh Steelers), and the West Division (Denver Broncos, Kansas City Chiefs, Oakland Raiders, and San Diego Chargers). The league season culminates with the Super Bowl, the annual championship game between the winners of the National and American conferences.
