Prior to the 1960s, industry and business interests dominated the debate about the impact of economic development and the environment. However, the visibility of environmental issues was raised dramatically by the growth of television as a national and international medium and by news-making environmental activists such as Rachel Carson, author of Silent Spring. Since the late 1960s, when scientists first speculated that supersonic aircraft would deplete the ozone layer, the mass media have played a major role in shaping awareness and perceptions of the scientific, diplomatic, commercial and technical challenges of protecting the ozone layer.2
