The article addresses debates around the introduction of commercial television in Britain, conducted in Parliament, lobby groups, the advertising trade press and broader cultural commentary. It notes that the boundaries between these interest groups were porous. The article refers to sample advertisements produced by agencies in anticipation of the 1955 launch of ITV in London and other regions thereafter, setting advertisers' initial caution against the bullishness subsequently checked by the 1962 report of the Pilkington Committee. ‘Americanisation’ is identified as a recurrent theme of anxiety, and advertising as a symptom of it, prompting complaints on both sides of the Atlantic. Many of the production strategies anticipated experimentally in the 1950s are with us still, as are concerns regarding differentiation of advertisements from programme content, advertisements' target audiences and commodities advertised on television. For legislators and advertisers alike, print media provided a model for imitation more often than did cinema. Competition between old and new platforms for advertisements – then as now – is identified as an opportunity for mutual advantage rather than displacement.
