The baby boom, the auto boom, the retailing boom, the media boom. Life in the postwar era seemed to be on constant fast forward, as we've tried to show in this section, and we chose to explore only some of the watershed changes that had their roots in the five years following the end of fighting in the Pacific on Aug. 14, 1945.
