The team was founded in 1959 as the Titans of New York, an original member of the American Football League; later, the franchise joined the NFL in the AFL–NFL merger. The team began to play in 1960 at the Polo Grounds. Under new ownership, the current name was adopted in 1963 and the franchise was relocated to Shea Stadium in 1964 and then to the Meadowlands Sports Complex in 1984. The Jets advanced to the playoffs for the first time in 1968 and went on to compete in Super Bowl III where they defeated the Baltimore Colts, becoming the first AFL team to defeat an NFL club in an AFL-NFL World Championship Game. Since 1968, the Jets have appeared in the playoffs thirteen times, and in the AFC Championship Game four times, most recently losing to the Pittsburgh Steelers in 2010. However, the Jets have never returned to the Super Bowl, making them one of three NFL teams to win their lone Super Bowl appearance, along with the New Orleans Saints and Tampa Bay Buccaneers.
