The Dallas Cowboys, also known as America’s Team, are a professional American football team based in the Dallas–Fort Worth metroplex. The Cowboys compete in the National Football League (NFL) as a member club of the league’s National Football Conference (NFC) East division. The team is headquartered in Frisco, Texas, and has been playing its home games at AT&T Stadium in Arlington, Texas, since its opening in 2009. The Cowboys joined the NFL as an expansion team in 1960. The franchise has made it to the Super Bowl eight times, tied with the Pittsburgh Steelers and the Denver Broncos for second most Super Bowl appearances in history, behind only the New England Patriots’ record. This has also corresponded to eight NFC championships, most in the NFC. The Dallas Cowboys have won five of those Super Bowl appearances. The Cowboys are the only NFL team to record 20 straight winning seasons (1966–85), in which they missed the playoffs only twice (1974 and 1984).
