The NBA three point line was moved up 3 feet for the 2006-07 season to 19 feet 9 nine inches at the top of the key and 19 feet two inches on the sideline. The NBA three point was moved back three feet for the 2007-08 season to its orignal length. The NBA introduced the three point line in the 1979-80 season at a length of 23'9" from the top of the key to a length of 22 feet in the corners. In the 1994-95 season, the NBA changed things so the three point line was a uniform 22 feet from the basket. The distance was reverted to 23'9" in the 1997-98 season and has been there ever since. The 19'9" distance is the distance of the College Basketball three point line, which will be changed to 20'9" for the 2008-09 season. The NBA three point line has never been set at 19'9".
