text: Despite this loss, 1966 marked the start of an NFL-record-setting eight consecutive postseason appearances for the Cowboys. (Dallas later broke its own record with nine consecutive trips to the playoffs between 1975 and 1983, a record that was tied by the Indianapolis Colts when they reached the playoffs every year from 2002 to 2010, and broken by the 2009-2019 New England Patriots.) It was also the beginning of a still NFL record streak of 20 consecutive winning seasons that extended through 1985. That same year, the Cowboys adopted the practice of hosting Thanksgiving games. It is widely rumored that the Cowboys sought a guarantee that they would regularly host Thanksgiving games as a condition of their very first one (since games on days other than Sunday were uncommon at the time and thus high attendance was not a certainty). This is only partly true; Dallas had in fact decided to host games on Thanksgiving by their own decision because there was nothing else to do or watch on that day. With exception of 1975 and 1977, the Cowboys have hosted a game every Thanksgiving Day since.
  In 1967, the Cowboys finished with a 9–5 record and had their first playoff victory, a 52–14 rout of the Cleveland Browns. They went on to face the Packers in the 1967 NFL Championship game, a rematch of the 1966 NFL championship game, with the winner advancing to Super Bowl II. The game, which happened on December 31, 1967, at Lambeau Field in Green Bay, turned out to be the coldest NFL game in history (about -13° F with a -40° wind chill). The Cowboys lost 21–17 on a one-yard quarterback sneak by Packers quarterback Bart Starr with 16 seconds remaining. The game later became known as the "Ice Bowl." Green Bay went on to win the Super Bowl again, this time against the Oakland Raiders.
