Submarine Telegraph Cables: Business and Politics, 1838–1939

International telecommunication is not only a business but also a political enterprise, the subject of great-power rivalries. In the late nineteenth century, British firms held a near monopoly, because Britain had more advanced industry, a wealthier capital market, and a merchant marine and colonial empire that provided customers for the new service. After the 1880s, they encountered increasing competition on the North Atlantic from American, German, and French firms. Elsewhere, the British conglomerate Eastern and Associated retained its hegemony until the 1920s. Following World War I, radiotelegraphy threatened the dominance of cables. In the 1930s, cable companies were almost bankrupted by the Depression and by competition from shortwave radio.
