Quick Answer: The Dallas Cowboys are a professional American football team based in the Dallas–Fort Worth metroplex. The Cowboys compete in the National Football League as a member of the National Football Conference East division. The team is headquartered in Frisco, Texas, and has played its home games at AT&T Stadium in Arlington, Texas, since its opening in 2009. The stadium took its current name prior to the 2013 season, following the team's decision to sell the stadium's naming rights to telecommunications company AT&T. The Cowboys joined the NFL as an expansion team in 1960. The team's national following might best be represented by its NFL record of consecutive sell-outs. The Cowboys' streak of 190 consecutive sold-out regular and post-season games began in 2002.
