This article explores the relationship between historicality and historiography, with particular focus on the tension between claims of the historicality of broadcast events and later absences in broadcast historiography. It analyses two types of claims of historicality: first as a provider of images of history in the making; and second, as a kind of prototype, a forerunner of a new era in which television has a central position in a global society. Looking at the production and organization of the broadcast of Yuri Gagarin's return to Moscow in April 1961, the article argues that historiography is often too bound up in the present and remains blind to perspectives falling outside the dominant narratives of the current. The claims of being forerunners, on behalf of the agents involved in producing the broadcast, fit poorly with later historical events and are perhaps nothing more than the ruins of an anticipated future. But as such it may teach us just as much about the forgotten aspects of television history as it does about our practices of writing it.
