The Washington Redskins are a professional American football team and members of the East Division of the National Football Conference (NFC) in the National Football League (NFL). The team plays at FedEx Field in Landover, Maryland, while its headquarters and training facility are at Redskin Park in Ashburn, Virginia. The Redskins have played over one thousand games since 1932. The Redskins have won five NFL Championships (two pre-merger, and three Super Bowls). The franchise has captured ten NFL divisional titles and six NFL conference championships. The Redskins won the 1937 and 1942 Championship games, as well as Super Bowls XVII, XXII, and XXVI. They also played in and lost the 1936, 1940, 1943, and 1945 Championship games, as well as Super Bowls VII and XVIII. They have made twenty-two postseason appearances, and have an overall postseason record of 23 wins and 17 losses. Only four teams have appeared in more Super Bowls than the Redskins: the Pittsburgh Steelers (eight), Dallas Cowboys (eight), Denver Broncos (six), and New England Patriots (six); the Redskins' five appearances are tied with the San Francisco 49ers, Oakland Raiders, Miami Dolphins, and Green Bay Packers. All of the Redskins' league titles were attained during two ten-year spans. From 1936 to 1945, the Redskins went to the NFL Championship six times, winning two of them. The second period lasted between 1982 and 1991 where the Redskins appeared in the postseason seven times, captured four Conference titles, and won three Super Bowls out of four appearances. The Redskins have also experienced failure in their history. The most notable period of failure was from 1946 to 1970, during which the Redskins did not have a single postseason appearance. During this period, the Redskins went without a single winning season between 1956 and 1968. In 1961, the franchise posted their worst regular season record with a 1–12–1 showing. According to Forbes Magazine, the Redskins are the second most valuable franchise in the NFL, behind the Dallas Cowboys, and were valued at approximately $1.55 billion as of 2009. Being the second most valuable franchise, the Redskins remain the highest grossing team in the NFL with $345 million in revenue during the 2009 season. They have also broken the NFL's mark for single-season attendance eight years in a row. The Redskins were the first team in the NFL with an official marching band. The other team with a marching band is the Baltimore Ravens, their regional rivals. The Redskins were the second team to have a fight song, "Hail to the Redskins".
