when did the three point shot start in basketball
Three-point field goal The three-point line was first tested at the collegiate 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. Its three-point line was a radius of 25 feet (7.62 m) from the baskets, except along the sides.[2] The Eastern Professional Basketball League followed in its 1963–64 season.
NCAA Division I Men's Basketball Tournament It has happened only once that all four No. 1 seeds made it to the Final Four:
Three-point field goal The NCAA's Southern Conference became the first collegiate conference to use the three-point rule, adopting a 22-foot (6.71 m) line for the 1980–81 season.[5][6] Ronnie Carr of Western Carolina University was the first to score a three-point field goal in college basketball history on November 29, 1980.[6][7][8] Over the following five years, NCAA conferences differed in their use of the rule and distance required for a three-pointer. The line was as close as 17 ft 9 in (5.41 m) in the Atlantic Coast Conference, and as far away as 22 feet in the Big Sky Conference.[9] Used in conference play, it was adopted by the NCAA for the 1986–87 men's season at 19 ft 9 in (6.02 m), and was first used in the NCAA Tournament in 1987.[10] In the same 1986–87 season, the NCAA adopted the three-pointer in women's basketball on an experimental basis, using the same 19 ft 9 in distance, and made its use mandatory beginning in 1987–88.[11] In 2007, the NCAA lengthened the men's three-point distance to 20 ft 9 in (6.32 m), with the rule coming into effect at the beginning of the 2008–09 season.[12] The NCAA women's three-point distance was moved to match the men's distance in 2011–12.[11] American high schools, along with elementary and middle schools, adopted a 19 ft 9 in (6.02 m) line nationally in 1987, a year after the NCAA.[13]
