question: When did the buffalo bills last make the AFL playoffs?
short_answers: 1966

context: The Bills began play as an original franchise of the American Football League (AFL) in 1960. The club joined the NFL as a result of the AFL–NFL merger for the 1970 season. The 1964 and 1965 Bills were the only teams representing Buffalo that won major league professional sports championships ("back-to-back" American Football League Championships). The Bills are the only team to win four consecutive conference championships and are the only NFL team to lose four consecutive Super Bowl games. The team was owned by Ralph Wilson from the team's founding in 1960, until his death in 2014 at the age of 95. After his death, Wilson's estate reached an agreement to sell the team to Terry and Kim Pegula, which was approved by the other NFL team owners on October 8, 2014. The Bills formerly possessed the longest active playoff drought in any of the four major professional sports in North America: they did not qualify to play in the NFL playoffs from 1999 until 2017 and were the last NFL team (and last team in the major North American professional sports leagues overall) to qualify for the playoffs for the first time in the 21st century.. Since then, the Bills have reached the playoffs in two of the past three NFL seasons and also clinched their first 10-win season in two decades in December 2019.
