<P> 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 , which went up to 107 points by its fourth year in use ( 1957 -- 58 ) . 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 . </P>
