T wenty-five years ago, George H.W. Bush was president, Michael S. Dukakis was governor, the Berlin Wall was dismantled, and Concord Computing Corp., a firm using computers to authorize checks cashed at supermarkets, was perched atop the first Globe 100.
Concord Computing has long since been rolled into an enterprise acquired by payment-processing giant First Data Corp. But the Globe 100 itself endured, becoming a unique window into the changing world of business in Massachusetts over a quarter century. Year by year, it chronicled the shifting dominance of local industries and emergence of promising new ventures. It also documented the staying power of some of the state’s most successful companies.
