Television is the most powerful system of images in the late 20th and early 21st centuries. Nonetheless TV has attained only little philosophical attention so far especially compared to other visual media such as film. This book looks at TV as what happens on the screen and beyond it which is mainly the operation of switching images. It therefore proposes a new definition of TV as the first picture that can be switched on off and over which stresses that TV is more tactile than visual. Through the operation of switching TV figures the world from within and as the course of its figuration. This is grasped here by the term of ontography the human response to the natural environment. Through the ongoing interlacing and bridging of TV 1.0 the image is being switched and TV 2.0 the image is a switch TV exponentially increases the production and circulation of images. It transforms the world and itself from an analogue state to a digital one and from central perspectivism to pluriperspective. In terms of time through switching and the switch it develops and reworks new temporal orderings such as instantaneity synchronicity flow and seriality. TV makes its own history. In space it creates a mediasphere as its habitat and hence new forms of beingintheworld of proximity and distance and scale. Anthropologically it works on what a subject and an object is on what makes the human being and ontographically how it is possible that there is something at all instead of nothing through switchimages.
