The three-point shot was introduced to a sizable audience when the American Basketball Association started in 1967 as a rival league to the NBA.
George Mikan, the Minneapolis Lakers great, was the first ABA commissioner and pushed the idea of a three-pointer.
The 6-10 Mikan saw it as an element that would give the "smaller player" a chance to have more of an impact on the game.
When Terry Pluto wrote his ode to the ABA, "Loose Balls: The Short, Wild Life of the American Basketball Association," Mikan said of the three-ball:
"We called it the home run, because the three-pointer was exactly that. It brought fans out of their seats."
The ABA's distance for the three-pointer for most of the court was 23 feet, 9 inches, which is the NBA's distance today.
Long ago it stopped being a home run — more like a two-out double — and it's not only made threes that bring fans out of their seats.
There are also the misses that cause some in the crowd to stand and shout: "What are you doing taking that shot?"
