Officiating and Procedures
Originally, there was one umpire to judge fouls and one referee to judge the ball; the tradition of calling one official the "referee" and the other one or two the "umpires" has remained (the NBA, however, uses different terminology, referring to the lead official as "crew chief" and the others as "referees"). Today, both classes of officials have equal rights to control all aspects of the game. The NBA added a third official in 1988, and FIBA did so afterward, using it for the first time in international competition in 2006. The use of video evidence to inform referee's decisions has always been banned, except in the case of determining whether or not the last shot of a period was attempted before time expired. This exception was introduced by the NBA in 2002 and adopted by FIBA in 2006. The NCAA, however, has permitted instant replay for timing, the value of a field goal (two or three points), shot clock violations, and for purposes of disqualifying players because of unsportsmanlike conduct. The NBA changed its rules starting in 2007 to allow officials the ability to view instant replay with plays involving flagrant fouls, similar to the NCAA. In Italy's Lega A, an American football-style coach's challenge is permitted to challenge (at the next dead ball) an official's call on any situation similar to the NCAA.
The center jump ball that was used to restart a game after every successful field goal was eliminated in 1938, in favor of the ball being given to the non-scoring team from behind the end line where the goal was scored, in order to make play more continuous. The jump ball was still used to start the game and every period, and to restart the game after a held ball. However, the NBA stopped using the jump ball to start the second through fourth quarters in 1975, instead using a quarter-possession system where the loser of the jump ball takes the ball from the other end to start the second and third periods, while the winner of that jump ball takes the ball to start the fourth period from the other end of the court.
In 1981, the NCAA adopted the alternating possession system for all jump ball situations except the beginning of the game, and in 2003, FIBA adopted a similar rule, except for the start of the third period and overtime. In 2004, the rule was changed in FIBA that the arrow applies for all situations after the opening tap.
In 1976, the NBA introduced a rule to allow teams to advance the ball to the center line following any legal time-out in the final two minutes of the game. FIBA followed suit in 2006.

Famous quotes containing the word procedures:
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
