Introduction
• signal traffic
• “the content and form of contemporary media . . . are shaped in relation to the properties and locations of these distribution systems” (1).
• how content moves and how movement affects content’s form.
• layering, path dependencies of “media infrastructures”
• “infrastructural disposition”:
(1) processes of distribution (not production emphasis)
(2) materialities of distribution
(3) tech literacies and public involvement
• Scale, Relationality, Difference and Unevenness, Labor/Repair/Maintenance, Natural Resources/Environment, Affect, Innovative Methodologies

Data Centers and the Cloud
• the cloud’s transparency as political metaphor? (75)
• media no longer a public good? (79)
• not just what is deliberately hidden, also what is made hypervisible (80)

Fixed Flow
• “Analyzing cables as media infrastructures involves articulating how they invisibly contort the conditions of possibility, geographic dispersion, and cultural perception of media signals” (55).
• (1) Cables “function as a resource for mediation”  (loop)
• (2) Cables alter “the temporality of information exchange”
• (3) Cables “implicate users within new and unseen structures of power” (disruption)
• (4) Cables “can perpetuate imbalances in media production and consumption” (inequality)
• “The user is not a rational agent who can locate herself in relation to such infrastructure; rather, she is a posthuman subject that extends across the network in multiple, unpredictable ways, intertwined with developments that are beyond any individual’s knowledge or control” (67).
