A three-point field goal is a field goal in a basketball game made from beyond the three-point line, a designated arc surrounding the basket. A successful attempt is worth three points, in contrast to the two points awarded for field goals made within the three-point line and the one point for each made free throw. In international FIBA and WNBA play, the three-point line is 6.75 m away from the basket on the arc part and 6.6 m from the straight parts. In both mens and womens National Collegiate Athletics Association basketball, the three-point line is simply a 180° circular arc centered on the basket,20 ft 9 in in radius. The three-point line was first tested at the level in a 1945 NCAA game between Columbia and Fordham but it was not kept as a rule. At the direction of Abe Saperstein, the American Basketball League became the first basketball league to institute the rule in 1961 and its three-point line was a radius of 25 feet from the baskets, except along the sides. The Eastern Professional Basketball League followed in its 1963–64 season, the three-point shot later became popularized by the American Basketball Association after its introduction in the 1967–68 season. Then commissioner of the ABA George Mikan stated the three-pointer would give the player a chance to score. During the 1970s, the ABA used the three-point shot, along with the slam dunk, in the 1979–80 season, the NBA adopted the three-point line despite the view of many that it was a gimmick. Chris Ford of the Boston Celtics is widely credited with making the first three-point shot in NBA history on October 12,1979, kevin Grevey of the Washington Bullets also made one on the same day. The sports international governing body, FIBA, introduced the three-point line in 1984, the NCAAs Southern Conference became the first collegiate conference to use the three-point rule, adopting a 22-foot line for the 1980–81 season. Ronnie Carr of Western Carolina University was the first to score a three-point field goal in basketball history on November 29,1980. Over the following five years, NCAA conferences differed in their use of the rule, used in conference play, it was adopted by the NCAA for the 1986–87 season at 19 ft 9 in, and was first used in the NCAA Tournament in 1987. In 2007, the NCAA lengthened the mens three point distance to 20 ft 9 in, with the coming into effect at the beginning of the 2008–09 season. American high schools, along with elementary and middle schools, adopted a 19 ft 9 in line nationally in 1987, a year after the NCAA. During the 1994–95, 1995–96, and 1996–97 seasons, the NBA attempted to address decreased scoring by shortening the distance of the line from 23 ft 9 in to a uniform 22 ft around the basket. From the 1997–98 season on, the NBA reverted the line to its distance of 23 ft 9 in. Ray Allen is currently the NBA all-time leader in career made three-pointers with 2,973, in 2008, FIBA announced that the distance would be increased by 50 cm to 6.75 m, with the change being phased in beginning in October 2010
