<P> The shot clock first came to use in 1954 in Syracuse , New York , where Syracuse Nationals ( now the Philadelphia 76ers ) owner Danny Biasone and general manager Leo Ferris experimented using a 24 - second version during a scrimmage game . According to Biasone , `` I looked at the box scores from the games I enjoyed , games where they did n't screw around and stall . I noticed each team took about 60 shots . That meant 120 shots per game . So I took 2,880 seconds ( 48 minutes ) and divided that by 120 shots . The result was 24 seconds per shot . '' Biasone and Ferris then convinced the NBA to adopt it for the 1954 -- 55 season , a season in which the Nationals won the NBA Championship . </P>
