The Tennessee Titans are an American football team based in Nashville, Tennessee. The Titans compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) South division. Previously known as the Houston Oilers, the team began play in 1960 in Houston, Texas, as a charter member of the American Football League (AFL). The Oilers won the first two AFL Championships, and joined the NFL as part of the AFL–NFL merger in 1970. The team relocated from Houston to Tennessee in 1997, and played at the Liberty Bowl Memorial Stadium in Memphis for one season. The team then moved to Nashville in 1998 and played in Vanderbilt Stadium. For those two years, they were known as the "Tennessee Oilers", but changed their name to "Tennessee Titans" for the 1999 season. The team currently plays at Nissan Stadium in Nashville, which opened in 1999 as Adelphia Coliseum. The Titans' training facility is at Saint Thomas Sports Park, a site at the MetroCenter complex in Nashville. Throughout the club's history, the Titans have played in the Super Bowl once (XXXIV, at the end of the 1999 NFL season); the Titans lost 23–16 to the St. Louis Rams.
