The British Electrical Development Association was formed by a group of engineers, generators and suppliers of electricity and electrical goods in order to co-ordinate sales and marketing campaigns effectively. The Association’s records include minutes, annual reports and advertising publications such as leaflets, posters and films designed to promote the use of electricity in the home and in the workplace. The records also include reports of annual sales conferences and a series of instruction manuals and handbooks. The Association became the Electrical Development Advisory Service of the Electricity Council in January 1966. The Council’s marketing department took over its functions from 1968 until privatisation.
