Revolution at the Checkout Counter is an absolute must for both business and food watchers. It deserves to be a classic. Stephen A. Brown, a Virginia attorney, was himself part of the plot, legally advising the pioneering grocery executives, many of whom he sketches. The tale he tells is riveting. He plots the people and companies who believed 30 years ago that there might be a value in having a universal product code to help data processing in the food trade This is a wonderful book, telling an astonishing story clearly. With the bar code, informatics came of age. Even the introduction by two Harvard Business School academics is a gem. -- Tim Lang * Times Higher Education Supplement * The Universal Product Codethe familiar bar code in consumer productsis one of the most pervasive technologies of the late twentieth century. This excellent book is the first substantial history of this important innovation The implementation of the bar code across the grocery manufacturing and retail industry was a phenomenal achievement of co-ordination and promotion.
