In recent years, the increasing adoption of digital technologies has dramatically accelerated the speed of change in the accounting information systems (AIS) domain. However, AIS go back centuries. This chapter provides a brief summary on the evolution of AIS, from when the first rudimentary versions of AIS were adopted to the Information Age with the adoption of mainframes and enterprise resource planning (ERP) systems to the present with the increasing adoption of business intelligence and data analytics capabilities. The technological development of AIS is also discussed in relation to how the role of accountants has changed over time.
