Steven J. Milloy is a tobacco and fossil fuel lobbyist who has frequently appeared in the media to spread doubt about the dangers of DDT, ozone destruction, secondhand smoke, climate change, and more. He pioneered the popular media strategy of calling research favorable to polluting industries as “sound science” and research hostile to it as “junk science.” He also helped organize the doubt-spreading industry, most notably by setting up a lobbying group called The Advancement of Sound Science Coalition for the Philip Morris tobacco company.
