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 (home and away) began in 2002. 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, just behind the New England Patriots record nine Super Bowl appearances. This has also corresponded to eight NFC championships, most in the NFC. The Cowboys have won five of those Super Bowl appearances, tying them with their NFC rivals, the San Francisco 49ers, and the AFC's Patriots; all three are second to Pittsburgh's record six 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 term "America's Team" is a nickname that refers to the Dallas Cowboys. The nickname originated with the team's 1978 highlight film, where the narrator (John Facenda) opens with the following introduction: They appear on television so often that their faces are as familiar to the public as presidents and movie stars. They are the Dallas Cowboys, "America's Team."
