History of TransUnion
TransUnion started as a holding company for railroad leasing, not credit. In the late 1960s, it acquired a small credit reporting company and recognized that consumer data would become more valuable than physical assets. This pivot was deliberate and strategic.

Incorporated utility, telecom, and public record data sources.
