Who Invented Three Point Line?

Chris Ford of the Boston Celtics is credited with making the first three-point shot in NBA history on October 12, 1979.

When was the 3-point line invented?

The league didn't adopt the 3-pointer until 1979--Magic Johnson and Larry Bird's rookie season. While certain college basketball conferences experimented with it in the early '80s, the NCAA didn't universally implement a 3-point line until 1986, with high school basketball following suit a year later.

Why are there two 3pt lines?

The NCAA says the rationale behind the decision is to: make the lane more available for dribble/drive plays from the perimeter. slow the trend of the 3-point shot becoming too prevalent in men's college basketball by making the shot more challenging, while at the same time keeping the shot an integral part of the game.
