“America’s team”: Since its winless opening season (with a single tie) in 1960, the Dallas Cowboys Football Club Ltd. has become the most valuable sports franchise in the United States, and one of the most successful. The Cowboys, winners of five Super Bowls, hold the National Football League record for the most post-season appearances. The franchise has amassed the longest streak of consecutive sold-out home and away games, and has accumulated more Monday Night Football victories than any other team. Beginning next season, the Cowboys’ home will be in Arlington, Texas, where they will do battle in the Metroplex, a new, state-of-the-art stadium.
