This chapter turns its attention to the underlying infrastructure that constitutes the material foundation of the global TV system. Technology is the application of science and knowledge to accomplish a task inside a domain, while infrastructure consists of the material elements that actualise it: it is the buildings, cables, servers, switches, and routers needed to transport data packets from point A to point B; it is the firms, machinery, engineers, and technicians who design, build, update, and repair these material components. This chapter examines the cloud infrastructure that sustains streaming, focusing on two key components: undersea cable networks and data centres. The final section describes the contours of the video ecosystem that technology and infrastructure have created, and within which television operates today.
