This chapter aims to introduce the reader with the transformative nature of the digital, which explains the scale and scope of current debates about the digital society. Beyond IT, or digital industries strictly speaking, the economy as a whole is transformed by digitization, which blurs the lines between traditional sectors, drives the globalization of value chains (VC), and shapes the geography of industries and firms. We examine more in depth how century-old sectors – banking, commerce, and manufacturing – are being 'disrupted' by digitization, with potentially important geographic consequences which, however, would probably not diminish the general tendency toward the spatial polarization of capital, high value-added business, skilled jobs, and wealth.
