Tobacco industry playbook

The tobacco industry playbook, also called the tobacco disinformation playbook or simply the tobacco strategy, describes a public relations strategy used by the tobacco industry in the 1950s to protect revenues in the face of mounting evidence of links between tobacco smoke and serious illnesses, primarily cancer. Such tactics were used even earlier, beginning in the 1920s, by the oil industry to support the use of tetraethyllead in gasoline.
