The Dallas Cowboys are a professional American football team located in the Dallas-Fort Worth Metroplex. The team is a member of the Eastern Division of the National Football Conference (NFC) in the National Football League (NFL). They are headquartered in Valley Ranch in Irving, Texas. The team plays its home games at AT&T Stadium in Arlington, Texas, which finished construction in time for the 2009 season. The Cowboys joined the NFL as a 1960 expansion team. The team's national following might best be represented by its NFL record of consecutive home sell-outs. The Cowboys' streak of 160 sold-out regular and post-season games began in 1990, and included 79 straight sellouts at their former home, Texas Stadium, and 81 straight sell-outs on the road. The franchise shares the record for most Super Bowl appearances (8) with the Pittsburgh Steelers and New England Patriots, corresponding to most NFC championships (8). The Cowboys won 5 of those, tying them with their NFC rivals, the San Francisco 49ers, both are second to Pittsburgh's record 6 Super Bowl championships. The Cowboys are the only NFL team to record 20 straight winning seasons (1966–85), in which they only missed the playoffs twice (1974 and 1984), an NFL record that remains unchallenged.
The Cowboys, at approximately $3.2 billion, are the most valuable NFL franchise according to Forbes, and the most valuable sports team in the United States. They are tied with soccer club FC Barcelona for the second-most in the world; only Real Madrid ($3.4b) is valued higher than the Cowboys. They also generate $560 million in revenue, again the most of any NFL team.
