With the spreading of digitization and the Internet, as well as the evolution of devices connected to it, the ability to collect, analyse and utilize data has made huge leaps recently. Numerous, often innovative business models ranging from data transport and data storage to sophisticated data analysis as well as insights creation are based on revenues essentially derived from data collection and use. This indicates a trend towards data becoming a new driver of economic growth, with a significant impact on business models. This chapter will therefore start by tracing technical innovations that have enabled better access to, as well as transport and utilization of, data. Each of these innovations has given rise to new business models that ultimately will result in a sustainable ongoing structural change in various markets, resulting in a data-driven economy that policy-makers and regulators need to be alert to.
