In the nearly two decades between the first transatlantic satellite television broadcast demonstration in 1962 and the rise of direct broadcast satellite service after 1980, the US and USSR developed two rival, intergovernmental satellite communications networks, the US-led INTELSAT and the Soviet-led Intersputnik. Yet this apparently typical story of Cold War competition and division conceals a much messier reality of interconnection, mutual influence, and shared anxieties that helped shape the future of both satellite communications and international cooperation in space from the early 1970s onward. Drawing on US and Soviet diplomatic and technical archives, interviews, and marketing and training materials, this talk explores what the history of communications satellite infrastructure can tell us about the Cold War and of the US-Soviet “space race.”
