To celebrate Toronto as a global city “on the rise”, the CN Tower opened on June 25, 1976. A significant piece of broadcasting and telecommunication infrastructure, the CN Tower became the world’s tallest freestanding structure upon its completion. Yet despite its imposing physical presence and its ubiquity in Toronto’s symbolic economy, there has been a virtual absence of research on the CN Tower within the media studies literature. This chapter recentres the CN Tower (specifically) and communication towers (generally) as critical forms of media infrastructure that are distinct from many more conventional “media buildings” in two key ways. First, in their ability to offer forms of verticality to the public, in the shape of spectacle and collective experience. Second, their mediality, as literal beacons that make use of expressive communication such as LED lighting and image projection to link political intention, technical function, and architectural pragmatism. Building on the work of Dana Mustata and other scholars, this chapter argues that communication towers can be useful for appreciating everyday experiences and unexcavated pieces of history in dimensional terms to better appreciate the mediatedness of the built environment.
