There are two sides to the process whereby families adopt personal computers. Computer usage diffuses between the household and outside state and market institutions. It also spreads between family members within the household. The focus of this chapter is on gender and generational differences in the process of the adoption of personal computers arising from a pilot study of thirty-nine families in a peripheral region of the national economy. The study was undertaken in Washington New Town in the north-east of England during 1989. 1 Thedo mestication of personal computer technology is considered in the light of an Institutionalist theory of value. The study of the process by which judgements about values are made in the context of the dynamic process of technological accumulation is seen as fundamental.
