Even if the high-tech and ‘revolutionary’ electric telegraph has become a favourite topic for communication historians dealing with global history, it cannot alone epitomize the first modern age of globalization.

By the end of the nineteenth century, millions of packets poured into post offices and railway stations, crossed countries, and created all sorts of transnational connections, from family to business to humanitarian relations. Behind the ordinary, seemingly low-tech small boxes lay a sophisticated service that emerged from transnational dynamics, challenged both national and international commercial circuits, and produced more complex control of economic borders.
