Extending broadcast technology in the British Colonies during the 1950s

Using a rich and under-exploited set of primary sources, differential rates of take up of radio broadcast technologies across the British Empire are described and explained. The research adds a developing economy perspective to the literature on the diffusion of consumer durables. The effects of prices and incomes (captured via an "affordability index") are qualified. The strategic concerns of suppliers and path-dependent processes are shown to have been significant. The complex effects of ethnic fragmentation on rates of diffusion within colonial territories are revealed. Debates regarding technological change in the developing world and about the diffusion of consumer durables are advanced.
