As a megacorporation, Alphabet is, by definition, an organizational agent of the highest degree. Nevertheless, it is neither entirely self-defined nor self-created. In particular, it has been shaped by the Silicon Valley context from within which it emerged. Accordingly, the chapter’s first section provides an overview of the key actors and sectors that have helped define, and mythologize, Silicon Valley. Following this, Google’s emergence, success and transformation are described and explained. Then, and in accord with the characteristics detailed in Chapter 2, Alphabet is shown to be a megacorporation. As Alphabet’s global scale and broad scope, monopolistic tendencies, corporate social responsibility concerns and political-economic hybridity are relatively simple to describe, the chapter’s summary notes that it is the megacorporation’s existential impacts – on the extent, and our experience of, the past and the future – that is focused on throughout the book’s second part.
