The computer promised business of the 1950s an administrative revolution. W
hat it delivered was data processing-a hybrid of new technology and existin
g punched card machines, people, and attitudes. The author examines how fir
st-generation computers were sold and purchased, and describes the occupati
ons (analyst, programmer, and operator) and departments that emerged around
them. This illuminates claims of a more recent electronic revolution in bu
siness.
