The Cowboys joined the NFL as an expansion team in 1960 under head coach Tom Landry (Landry, Tom). After posting a losing record in each of their first five seasons, the Cowboys quickly became one of the NFL's better teams, qualifying for the play-offs in 17 of the 18 seasons between 1966 and 1983. The Cowboys joined the Detroit Lions in hosting an annual home game on Thanksgiving Day in 1966, a move that greatly increased the team's national exposure. In 1967 Dallas reached the NFL championship game but lost to the Green Bay Packers in a contest that featured the lowest recorded on-field temperature in NFL history (–13 °F 【–25 °C】) and became known as the “Ice Bowl.” Future Hall of Fame quarterback Roger Staubach (Staubach, Roger) arrived in 1969 and went on to establish the Cowboys as a perennial title contender. With Staubach the Cowboys won five NFC championships and two Super Bowls (1972, 1978), and the popular franchise, which also boasted scantily clad cheerleaders who were both sex symbols and the targets of feminist scorn, became known by the nickname “America's team.” Other notable players of the Landry era included defensive tackles Bob Lilly and Randy White, wide receiver and former Olympic sprint champion Bob Hayes (Hayes, Bob), cornerback Mel Renfro, and running back Tony Dorsett.
