When the ticker was replaced by the monitor. A lecture on the information architecture of the global financial market.

In this enlightening lecture, sociologist Karin Knorr Cetina elaborates on three developmental stages in technology that enable the global financial market, and the foreign exchange market in particular. Through her explorations of streams, scopes, symbols, and the algorithms mobilizing these, she describes the conceptual and temporal worlds used to trade currencies and pollution certificates and what kind of credit-based technosphere arises from their systemic enclosures.
