This chapter examines the role played by pneumatic tubes in transmitting stories and story content (notes, assignment slips, etc.) in twentieth-century North American newsrooms. First developed for commercial use in Victorian Britain, pneumatic tubes have a long history of use in newsrooms. That use represented the then-state-of-the-art in the journalism industry, growing up alongside telephones as a means of sharing copy within newsroom spaces. In time, their use would fade in favour of cables and wires—the hidden infrastructure of the modern newsroom, and, indeed, our information society—but pneumatic tubes were an important predecessor technology and shaped news flows. As part of the space and place of the newsroom, in that sense, they helped to literally and figuratively tether the production and editorial sides of newspapers. Relying on a close examination of trade publications such as Editor & Publisher and Quill, the in-house publication of the Society of Professional Journalists (SPJ), this chapter demonstrates how pneumatic tubes served as an important transitionary technology (in the sense that they operated in an in-between era of great change in newsroom culture), and one worthy of deeper examination in its own right.
