The Material Politics of Finance: The Ticker Tape and the London Stock Exchange, 1860s–1890s
本文研究19世纪60至90年代伦敦证券交易所和电报公司如何通过股票行情自动收录器的物质基础设施（如电池、电路、线缆）集中控制金融信息分发，导致信息不平等，并引发关于信息获取权的政治问题。
When the ticker tape was first invented in the 1860s, it promised a revolution in financial markets. Pricing information was now no longer solely the domain of the trading floor but was relayed continuously and simultaneously to ticker tapes long distances away from the stock exchange. Both nineteenth-century financiers, and the modern scholars who study them, have been enamored with the ticker tape and how it changed the way financial markets were perceived and experienced. However, a focus on how nineteenth-century financiers read and responded to the ticker tape has missed the real reordering of power that the ticker helped usher in. This article argues that between the 1860s and 1890s the London Stock Exchange and the Exchange Telegraph Company powerfully centralized their control over the distribution and transmission of financial information through the mundane infrastructures that underpinned the ticker tape system. Seeming technicalities, like the placement of batteries, the construction of electrical circuits, and the laying of wires and cables, were leveraged by these institutions to create a ticker tape system that distributed financial information unequally to financiers and investors throughout Britain. By the end of the nineteenth century, social and political questions about who should have access to financial information and markets, and on what terms, became helplessly intertwined with the mundane technicalities of the material infrastructures of modern finance.
