when did the nba institute the shot clock
Shot clock The shot clock, together with some rule changes concerning fouls, revolutionized NBA basketball. In the last pre-clock season (1953–54), teams averaged 79 points per game; in the first year with the clock (1954–55), the average was 93 points,[3] which went up to 107 points by its fourth year in use (1957–58).[11] The advent of the shot clock (and the resulting increase in scoring) coincided with an increase in attendance, which increased 40% within a few years to an average of 4,800 per game.[12]
