This presentation proposes to explore the relations between three distinct yet overlapping infrastructures in contemporary Tokyo: broadcast television, mobile phones or keitai, and the commuter train network. The basic aim is to how consider the lived experience of polarized medial tendencies between and across these infrastructures. While a variety of everyday comportments have arisen between broadcast television and keitai, there are sites and moments where comportment seems to reach a limit, and life across polarized
tendencies feel impossible, unworkable.
